The Hotel is located at 7000 feet above sea level on Marghazar Hill Swat valley offers beautiful views and good service and good food. Hotel White Palace has a rich historical background built in 1941 as the summer resort for the King of Swat, Hotel White Palace is the place which was desired & admired by Artisan, Scholar, King and Queens. The resort is located in SWAT Valley. The Chinese pilgrims in the 5th & 6th century called it the Valley of Hanging Chains. At one time, SWAT, represented the famous GANDHARA CIVILIZATION. Hotel White Palace, built in 1941 by King Wadood as a summer house, was a proud host to Queen Elizabeth as a guest. Enjoy a relaxing vacation - angling for Swat river trout & local tours to Archaeological sites. For the more active, try golf, hunting or skiing. During the season, savior apples, apricot, pears etc. within resort compound. Queen Elizabeth of Great Britain stayed at White Palace
for three days, as she
discovered the deep traditions & history which surround the Swat Valley. Even the marble used in the palace have the significance, coming from the same quarry that supplied the Taj Mahal. The longer you stay, the richer your experience will become as you discover all that the Swat Valley has offer.

Present System
CHAPTER 2
2.1 THE PRESENT SYSTEM The current reservation system of Hotel White Palace is a manual system. In order to make a computer based online Reservation system, we first check the current system so that we get to know about the flaws and shortcomings in this system. This study will help us to design such a computerized online system of reservation which would be free of all the flaws, now present in this manual system of the Hotel and will facilitate both the customers as well as the administrative staff of the Hotel White Palace. The present manual system of reservation Process is only to determine Basic Room Availability. That is to say, the reservation clerk can only tell the potential guest that a room is reserved for him/her. However, the reservation clerk can not tell the customers the type of the room and rate. At last, in the case of present manual system all the record is kept in document form. There is no system for proper record storage and sorting the information provided by the customers. All this is done manually and every now and then, there is a chance of getting erratic information. The manual system is thus no guarantee.
2.3 The reservation procedure Reservation process consists of the following steps: Guests can communicate their reservation inquiries in person, over the telephone, via mail, through facsimile, telex, e-mail… Moreover, reservation inquiries can be made through a Central Reservation System or an Intersell Agency. While getting a reservation inquiry, the reservation agent obtain the following guest-related information: a) b) c) d) e) f) g) h)
Guest’s name, address and telephone number Company or travel agency name Date of arrival and departure Type and number of rooms requested Desired room rate Number of people in the group, if applicable Method of payment and/or guarantee Any other special requests

Proposed System
CHAPTER 3 3.1 PROPOSED SYSTEM After the detailed study of current system, it is good to propose a new system. As computer is one of the leading technologies now a day, so we proposed a computer-based system, which fulfill all the requirements of the organization easily and will be the solution to the problem faced by manual system. The computerization of a system means to change it from manual to a computer-based system. To audiometer the work and to provide efficiency, accuracy, timelessness, security and economy. A computer-based system is a tool, which can help the management to exercise an Effective and timely decision-making.
3.2 OBJECTIVES OF THE PROPOSED SYSTEM Before designing any computer-based system, it is necessary to establish the objectives that proposed system should satisfy. The relative important of each objective also needs to establish. An effective system is proposed with the following features The proposed system is replacement of the existing system, which is conventional. The proposed system should be more efficient and useful than the existing manual system. It should minimize the time involved in processing and retrieval of information. It should be error free and provide accurate information. The new computer-based system should have the capacity to store and manipulate data entered into it. The proposed system should comprehensive database, which provides access, insertion, updation and deletion on each file and facilitate online queries and data promoting at where cursor is placed. The new system should be simple so that its structure, operation and procedure should be maintained easily. 8 Online Reservation System of Hotel White Palace Swat
Chapter 3
Proposed System
The system should be sufficiently flexible, to cope with future requirements, i.e. system should support large amount of data, which will be increasing in future with the passage of time very efficiently. The system should be user friendly and menu driven so that any data entry operator can easily enter the data and the management can get the reports easily and the computer screens should guide the user, where to find the required menu. The proposed system should minimize the data redundancy, which frequently occurs in non-computerize system. The proposed system enables the management to get adhoc reports for making quick decisions, which are not possible in manual system
3.3
FEATURES OF THE PROPOSED SYSTEM
Primary 1) To animate the process of addition/updating of data files. 2) To remove the possibility of data redundancy. 4) To develop the user-friendly system. User interface For better user interaction, whether operator or executive, interactive inputs screen is well designed. They would make data entry simple and easy for the user and data will be accepted in the same manner as it is done manually but in a much attractive way. Updating This facility should be provide to update the field of the record in the system in updation, user could change any field of the record except, the key field of the existing records. Data validation Various checks should be provide in the database for the data entry updation to ensure data security and validity. Data validation checks would be provided to ensure that no duplicate
9 Online Reservation System of Hotel White Palace Swat
Chapter 3
Proposed System
keys are allowed to be entered. In an attempt to enter a record thus eliminate the chance of duplications. Similarly all coded fields are checked for valid range of values and error messages. Generality The good quality of the proposed system is that it can be used in almost every organization, whether it is institutional, public or personal sector. Simple to use The program requires no special training for its operation, because it is user friendly and communicates with user in simple English language. Thus any person who has some knowledge of computer and English language can use it. Updation of records The system provides updating facility. The user can update any of the candidate record. Deletion of records The system also provides deletion facility. The user can delete any of the record etc, if he/she is authorized. Data handling The present manual system requires stationary for the entry of data. There is therefore a greater chance of mistakes leading to errors, which result in system inefficiency and inadequacy. In proposed system data validity checks have been incorporated to minimize the chances of entering incorrect data. Backup facility A backup facility is provided which helps in making the duplicate copy of the data year wise. In case of any damage to data by virus (these are malicious programs which attach itself to other programs) or power failure the whole record can be fed into the computer again Search facilities Search facilities are provided as Search by name, the system can display the total number of records matching that name at the moment. Bio Data of Members By entering password, being an authorized user the complete bio data of Member can be seen

Proposed System
3.4 Project Feasibility Definition Feasibility study is a test of a system proposal according to its workability, impact on the organization, ability to meet user needs and effective use of resources. The data collected during the preliminary investigation determine the project feasibility i.e. whether the system will be beneficial to the organization.
It focuses on three major questions: What are the user’s demonstrable needs and how does a candidate system meet them? What resources are available for a given candidate system? Is the problem worth solving? What are the likely impacts of the system on the organization? Operational feasibility Operational feasibility depicts whether a system will work successfully whenever developed & installed. There is sufficient support for the new system from management. ii) The current method is not acceptable to the user. So user may welcome a change that will bring more operational & useful system. The proposed system will not cause any poor result in any section. The accessibility of information will not be lost are delayed. Performance will neither be slow nor insecure in any system. Technical feasibility Technical feasibility is concerned with the technology The necessary technology requirement IBM PIV along with a laser Printer, double drive, a mouse and at least 40 GB hard disk. The proposed equipment has the technical capability to hold the data required to use the new system. System can be expanded whenever required. There are technical guarantees of accuracy, reliability, ease of access and data security. Financial and Economic Feasibility It is also known as cost/benefit analysis, the procedure is to determine the benefits and saving that are expected from a present system and compare them with cost. 11 Online Reservation System of Hotel White Palace Swat

CHAPTER 4 4.1 Introduction The system is developed to the user’s point of view using hardware and software components that required supporting the system is designed. Program functional specifications are to describe all functions performed by each program. Database dictionary, single sources that define the names and contain all data elements in the system are also included. For this purpose we use ASP as background for the database connectivity and HTML as front end for the forms and JavaScript for the programming. The selection of the software for the designing the application is important and it depends upon the requirement. After analysis various languages, and tools are selected which are discussed as follows.
4.2 HTML The explosive growth of the World Wide Web is relatively unprecedented, although it resembles the desktop publishing revolution of the early and mid-1980s. As personal computers became more common in homes and offices, people began to learn to use them for document creation and page programmer. Although early word processing programs were not terribly intuitive and often required memorizing bizarre codes, people still picked them up fairly easily and managed to create their own in-house publications. Suddenly, the same kind of growth is being seen as folks rush to create and publish pages of a different sort. To do this, they need to learn to use something called the Hypertext Mark-up Language (HTML).
History of HTML HTML developed a few years ago as a subset of SGML (Structure Generalized Mark-up Language), which is a higher-level mark-up language that has long been a favorite of the Department of Defense. Like HTML, it describes formatting and hypertext links, and it defines different components of a document. HTML is definitely the simpler of the two, and although they are related, there are few browsers that support both. 12 Online Reservation System of Hotel White Palace
Chapter 4
Description of the tools
Because HTML was conceived for transmission over the Internet (in the form of Web pages) it is much simpler than SGML, which is more of an application-oriented document format. While it's true that many programs can load, edit, create, and save files in the SGML format (just as many programs can create and save programs in the Microsoft Word format), SGML is not exactly ideal for transmission across the Internet to many different types of computers, users, and browser applications. HTML is more suited to this task. Designed with these considerations in mind, HTML lets user, the designer, create pages that user are reasonable, sure can be read by the entire population on the Web. Even users who are unable to view user graphics, for instance, can experience the bulk of what user are communicating, if user design, user HTML pages properly. At the same time, HTML has a simple enough format (at least currently) that typical computer users can generate HTML documents without the benefit of a special application. Creating a WordPerfect-format document would be rather difficult by hand (including all of the required text size, font, page break, column, margin, and other information), even if it weren't a "proprietary"—that is, nonpublic—document format. HTML is a public standard, and simple enough that user can get through a book like this one and have a very strong ability to create HTML documents from scratch. This simplicity is part of a trade-off, as HTML-format documents don't offer nearly the precision of control or depth of formatting options that a WordPerfect- or Adobe PageMaker-formatted document would.
4.3 Hypertext Preprocessor PHP, or Hypertext Preprocessor, is a widely used, general-purpose scripting language that was originally designed for web development, to produce dynamic web pages. It can be embedded into HTML and generally runs on a web server, which needs to be configured to process PHP code and create web page content from it. It can be deployed on most web servers and on almost every operating system and platform free of charge. PHP is installed on over 20 million websites and 1 million web servers. 13 Online Reservation System of Hotel White Palace

PHP was originally created by Rasmus Lerdorf in 1995 and has been in continuous development ever since. The main implementation of PHP is now produced by The PHP Group and serves as the de facto standard for PHP as there is no formal specification. PHP is free software released under the PHP License, which is incompatible with the GNU General Public License (GPL) because of restrictions on the use of the term PHP. PHP has evolved to include a command line interface capability and can also be used in standalone graphical applications.
4.4 Scripts A script is a series of sentences placed one below the other in the form of a paragraph. each sentence tells the CPU what it should be doing at that moment in time, the sentences will be written in the syntax (grammar) of the scripting language of choice thus the paragraph created (which clubs together all the sentences) will be the script. A script for example: Assign a value to a variable: A variable is a named storage location that can hold data Instruct the Web Server to send something: Such as the value of a variable, to a browser. Combine commands into procedures: A procedure is named sequence of commands and statements that acts as a unit. Executing a script sends the series of commands to a script engine, which interprets and relays them to the computer’s CPU. Scripts are written in languages that have specific
JavaScript JavaScript is a new scripting language that is being developed by Netscape. With JavaScript programmer can easily create interactive web pages. Many people believe that JavaScript is Java because of the similar names. This is not true though. What is needed in order to run scripts written in JavaScript? Programmers need a JavaScript-enabled browser. Of course programmers’ need a basic understanding of HTML before programming in java script.

4.5 Dreamweaver: Adobe Dreamweaver (formerly Macromedia Dreamweaver) is a web development application originally created by Macromedia, and is now developed by Adobe Systems, which acquired Macromedia in 2005. Dreamweaver is available for both Mac and Windows operating systems. Recent versions have incorporated support for web technologies such as CSS, JavaScript, and various server-side scripting languages and frameworks including ASP, ColdFusion, and PHP.
4.6 MySQL MySQL is a relational database management system (RDBMS) that has more than 6 million installations. MySQL stands for "My Structured Query Language". The program runs as a server providing multi-user access to a number of databases. The project has made its source code available under the terms of the GNU General Public License, as well as under a variety of proprietary agreements. MySQL is owned and sponsored by a single for-profit firm, the Swedish company MySQL AB, now a subsidiary of Sun Microsystems. As of 2009 Oracle Corporation began the process of acquiring Sun Microsystems. MySQL is often used in free software projects that require a full-featured database management system, such as WordPress, phpBB and other software built on the LAMP software stack. It is also used in very high-scale World Wide Web products including Wikipedia, Google and Facebook.

4.7 Cascading Style Sheets (CSS) CSS is a style sheet language used to describe the presentation semantics (that is, the look and formatting) of a document written in a markup language. Its most common application is to style web pages written in HTML and XHTML, but the language can be applied to any kind of XML document, including SVG and XUL. CSS is designed primarily to enable the separation of document content (written in HTML or a similar markup language) from document presentation, including elements such as the layout, colors, and fonts. This separation can improve content accessibility, provide more flexibility and control in the specification of presentation characteristics, enable multiple pages to share formatting, and reduce complexity and repetition in the structural content (such as by allowing for tableless web design). CSS can also allow the same markup page to be presented in different styles for different rendering methods, such as on-screen, in print, by voice (when read out by a speech-based browser or screen reader) and on Braille-based, tactile devices. While the author of a document typically links that document to a CSS style sheet, readers can use a different style sheet, perhaps one on their own computer, to override the one the author has specified. CSS specifies a priority scheme to determine which style rules apply if more than one rule matches against a particular element. In this so-called cascade, priorities or weights are calculated and assigned to rules, so that the results are predictable.
Use of CSS Prior to CSS, nearly all of the presentational attributes of HTML documents were contained within the HTML markup; all font colors, background styles, element alignments, borders and sizes had to be explicitly described, often repeatedly, within the HTML. CSS allows authors to move much of that information to a separate style sheet resulting in considerably simpler HTML markup.
17 Online Reservation System of Hotel White Palace
Chapter 4
Description of the tools
Headings (h1 elements), sub-headings (h2), sub-sub-headings (h3), etc., are defined structurally using HTML. In print and on the screen, choice of font, size, color and emphasis for these elements is presentational. Prior to CSS, document authors who wanted to assign such typographic characteristics to, say, all h2 headings had to use the HTML font and other presentational elements for each occurrence of that heading type. The additional presentational markup in the HTML made documents more complex, and generally more difficult to maintain. In CSS, presentation is separated from structure. In print, CSS can define color, font, text alignment, size, borders, spacing, layout and many other typographic characteristics. It can do so independently for on-screen and printed views. CSS also defines non-visual styles such as the speed and emphasis with which text is read out by aural text readers. The W3C now considers the advantages of CSS for defining all aspects of the presentation of HTML pages to be superior to other methods. It has therefore deprecated the use of all the original presentational HTML markup.
4.8 Adobe Flash Mx Adobe Flash (formerly Macromedia Flash) is a multimedia platform originally acquired by Macromedia and currently developed and distributed by Adobe Systems. Since its introduction in 1996, Flash has become a popular method for adding animation and interactivity to web pages. Flash is commonly used to create animation, advertisements, and various web page Flash components, to integrate video into web pages, and more recently, to develop rich Internet applications. Flash can manipulate vector and raster graphics, and supports bidirectional streaming of audio and video. It contains a scripting language called ActionScript. Several software products, systems, and devices are able to create or display Flash content, including Adobe Flash Player, which is available free for most common web browsers, some mobile phones and for other electronic devices (using Flash Lite). The Adobe Flash Professional multimedia authoring program is used to create content for the Adobe Engagement Platform, such as web applications, games and movies, and content for mobile phones and other embedded devices. 18 Online Reservation System of Hotel White Palace

Files in the SWF format, traditionally called "ShockWave Flash" movies, "Flash movies" or "Flash games", usually have a .swf file extension and may be an object of a web page, strictly "played" in a standalone Flash Player, or incorporated into a Projector, a selfexecuting Flash movie (with the .exe extension in Microsoft Windows or .hqx for Macintosh). Flash Video files[spec 1] have a .flv file extension and are either used from within .swf files or played through a flv-aware player, such as VLC, or QuickTime and Windows Media Player with external codecs added.
4.8 Adobe Photoshop Adobe Photoshop, or simply Photoshop, is a graphics editing program developed and published by Adobe Systems. It is the current market leader for commercial bitmap and image manipulation software, and is the flagship product of Adobe Systems. It has been described as "an industry standard for graphics professionals" and was one of the early "killer applications" on the Macintosh, later also for MS Windows. Adobe's 2005 "Creative Suite" rebranding led to Adobe Photoshop 8's renaming to Adobe Photoshop CS. Thus, Adobe Photoshop CS4 is the 11th major release of Adobe hotoshop. The CS rebranding also resulted in Adobe offering numerous software packages containing multiple Adobe programs for a reduced price. Adobe Photoshop is included in most of Adobe's Creative Suite offerings. Photoshop's popularity, combined with its high retail price, makes Photoshop's piracy rate relatively high. Adobe countered by including SafeCast DRM starting with Adobe Photoshop CS.
4.9 Apache web server The Apache HTTP Server is a web server for Unix-like systems, Microsoft Windows, Novell NetWare, Mac OS X and other operating systems. Apache is notable for playing a key role in the initial growth of the World Wide Web. When first released, Apache was the only viable open source alternative to the Netscape Communications Corporation web server (currently known as Sun Java System Web 19 Online Reservation System of Hotel White Palace

Server). It has since evolved to rival other Unix-based web servers in terms of functionality and performance. Since April 1996 Apache has been the most popular HTTP server on the World Wide Web; as of February 2007 Apache served 58% of all websites. Apache is developed and maintained by an open community of developers under the auspices of the Apache Software Foundation. Released under the Apache License, the Apache HTTP Server is free software.

5.3 Logical design Logical design describes the detail specification for the proposed/new system. We can say that it describes its own features. Input, output, file (table) and database in a manner that meets the project needs. Logical design is formulated when detailed specifications for the new system are written. Therefore from the new system specification we can know how the inputs, outputs, files, database and procedures should be designed so that it satisfies the user requirements.

System Design
In logical design work with user is done to develop general system design, choose best design, develop system flow charts, identify hardware, software and personal needs and revise estimates etc.
5.4 Physical design Physical design is a program written in a programming language that takes input, process it and gives output in the form of reports and also stores the data. In other words, the logical design is implemented in physical form in this phase. Physical design refers to the practical work, which is described in logical design. It includes application development i.e. software development/user interface etc. in physical design we do technical design, plan program modules algorithm, files, databases, I/O forms.
5.5 Input design The input design specifies the number in which the user enters the data to the system for processing at later stages. Input design can ensure the reliability of the system and provide accurate data. The input determines weather the user interacts with the system efficiently or not. The input design can also be explained as link between the user and the world. Input design consists of those steps necessary to put transaction data into usable for processing data entry and activity of submitting the data into computer for processing. A lot of care is required while entering the data. The reason is that invalid input results in invalid outputs. While designing the input for the Hotel White Palace, I kept the following objectives in mind as guidelines. Reducing the amount of data Avoiding errors in data Avoiding extra steps Keeping process multiple Avoiding delays In my project, input is the information about the customers, general clients communicating through feedback facility. The operators enter this information . 25 Online Reservation System of Hotel White Palace
Chapter 6
System Design Homogenous data elements
I have take special care in order to make the nature of all the data elements to be same, so that they all are relevant with the customer information and no irrelevant data is included. This helps in keeping the main focus on the information related to customer only. Input forms design The forms used to take the inputs are designed in a simple way. All the logically related items are grouped together or tried to place near each other, so that the user has no difficulty in filling the form. Screen display While displaying the reservation forms on the screen all the data elements included in the forms are well separated from each other, so that the user feels no difficulty in viewing, finding and filling in the required information.
5.6 INPUT VALIDATION Input validation is a general term given to methods, aimed at detecting errors in the input. The main thing, which is considered in the input, is that what the chances of errors are. Following are input validation used for designing the admission system for Hotel White Palace: Empty entry control Data Type Validation
5.7 OUTPUT DESIGN Another step in designing a system is to design its output according to the requirements of the user .the phase of output design has great importance because inadequate outputs indicate the overall system to be designed poorly. A system is considered to be successful or failed on the basis of output design. The term “Output” means after the completion of physical design what comes out of the computer system for the user? The output design in project is considered as the backbone of the project. The major form of output is a hard copy from the printer. All managerial decision is actually

made through these reports. Basically the reports in responses to queries and then reports can be printed. I took the following points into consideration while designing the output. Outputs required Required data elements Length of data elements Who will receive the output How much detail is needed Data type of the data element.

6.1 Logical Database Design The basic and important step in the database development process is Database Analysis, in which we determine user requirements for data and develop data models to spycify those requirement. A conceptual data model is one that Represent data from the viewpoint of the user independent of any technology that will be used to implement the model. For conceptual data modeling there are different techniques. 1. The Entity-relationship Model
Object relationships among these objects. It is intended primarily for the DB design process by allowing the specifications of an enterprise Scheme. This represent the overall logical structure of the DB. An E.R model is a detailed, logical representation of the data for an organization or for a business area. The ERD is notation that is used to conduct the data modeling activity. Using ERD the software engineers creates a representation all data objects that are important for the system. Representing “Data Network “that exists for a given system.
6.2.1 Object-Oriented Modeling The main concepts and techniques involved in the object-oriented modeling, including objects and Classes, encapsulation of attributes and operations, associations,

generalization, and aggregation relationships; cardinalities and other types of constraints; polymorphism; and inheritance.
6.2.2 Key Elements of ERD Entities/Data objects Attributes Relationships
6.2.3 Entity/Data object Entity: a person, place, object, event, or concept in the user environment about which the organization wishes to maintain data. Examples in Reservation are: Person: Customer. Place: Room. Object: item Event: sale Concept: Account Entity Type: a collection of entities that share common properties or characteristics. For example, Customer, Room..In ERD it is represented by rectangle. Each entity type in an E-R model is given a name. Since the name spycify a class, it is singular; we use capital letters in naming an entity type. In an E-R diagram, the name is replaced inside the box representing the entity:

Entity Instance: A single occurrence of an entity, figure illustrates the distinction between an entity type and one of its two instances. Any entity type is described just once in a database, while many instances of that entity type may be represented by data stored in the database. For example, there is one CUSTOMER entity type, but there may be hundreds of instances of this entity type that are store in that database. For example, CUSTOMER is entity and CUSTOMERid “id” is its instance Entity Instance: A single occurrence of an entity, figure illustrates the distinction between an entity type and one of its two instances. Any entity type is described just once in a database, while many instances of that entity type may be represented by data stored in the database. For example, there is one CUSTOMER entity type, but there may be hundreds of instances of this entity type that are store in that database. For example, CUSTOMER is entity and CUSTOMER id “id” is its instance. STRONG ENTITY TYPE VS WEAK ENTITY TYPE: Strong Entity type: An entity type that exists independently of other entity types, e.g. CUSTOMER.
SYMBOL Strong Entity type Weak Entity Type:

An entity type whose instances depend on some other entity type. A weak entity type has no business meaning and is not needed in the E-R Diagram. In ERD weak entity type is represented by double lined rectangle. SYMBOL Weak entity type Identifying Owner: The entity on which weak entity depends is called identifying owner or Owner. Identifying Relationship: The relationship between a weak entity type and its owner is called identifying Relationship. Data object A data object is almost any composite information that must understood by software. By composite information we mean that something that has a number of different properties or attributes. ATTRIBUTES Attributes define the properties of a data object and take on one of three different characteristics. They can be used to Name an instance of the data object. Describe the instance. Make a reference to another instance in another table. SYMBOL
Attribute For Example, the entity type CUSTOMER has attributes i.e. name, nic, custid etc. Composite Attribute:

CARDINALITY OF RELATIONSHIP: Specify the number of instances of one entity that can be associated with each
instance of another entity. MINIMUM CARDINALITY: The minimum number of instances of one that may be associated with each instance of another entity. MAXIMUM CARDINALITY: The maximum number of instances of one entity that may be associated with a single occurrence of another entity. If the minimum cardinality is zero the participant is optional and if the minimum cardinality is one the cardinality is mandatory.

6.5 FUNCTIONAL ANALYSIS AND MODELING: The functional analysis and modeling focuses on the main functions of the system and the detailed functionality. The main entity in the functional analysis modeling is flow model. THE FLOW MODEL IS DISCUSSED AS: 1.
Information is transformed as it flow through the computer based System.
2.
The system accepts input in a verity of forms from external world. Apply hardware, software and human element to transformed input into output,
and produces the output in a variety to the external world. Structured analysis began as an information flow modeling technique .A computer based system is represented as information transforms. Overall function of the system may be represented as information transformed. 6.6 DATA FLOW DIAGRAM: As information moves through software, it is modified by a series of transformations. A DFD is a graphical technique that depicts information flow and transform data replied as data moves from the input to output. DFD is also known as data flow graph .A DFD may be used to represent the system or software at any level of abstraction. Infect DFD may be partitioned into levels that represent increasing information flow and functional detail. Therefore DFD provides mechanism for functional modeling as well as functional modeling.

Data dictionary overview Data dictionary in database management system is a file that defines the basic organization of a database; it contains a list of all files in database, the number of records in each file and the names and types of each field. Most database management system keeps the data dictionary hidden from users to prevent them from accidentally destroying its contents. In any database management system [DBMS], you have many objects tables, indexes, etc and many other things going on. The database needs to keep track of all these things. It does this with the help of something called the data dictionary. The data dictionary is a structure that stores meta-data, or data about data. Data dictionary is actually the memory of the database where he keeps all the activities going on in the database and retrieves that information in the future for further processing. It is actually the data dictionary, which keeps the information about database objects, its security and auditing. Data stored as fields and different database files along with their fields name, type and size.

CHAPTER 9
SYSTEM TESTING 8.1 Testing Strategies Development of a software system involves a series of production activities where opportunities for injection of human fallibilities are enormous. Errors may begin to occur at the very inception of the process where the objectives may be erroneously of imperfectly specified, as well as in the later design and development stages. Because of human inability to perform and communicate with perfection, software development is accompanied by a quality assurance activity, Software Testing. Software testing is a critical element of software quality assurance and represents the ultimate review of specification, design and coding. The basic testing strategies are as follow
Unit testing
In the unit testing different modules of the system are tested
separately. The
purpose of this testing is to determine that each module is functioning properly and to locate error in modules. In unit testing we can locate and remove error easily. We have tested different modules of our system individually; note that each is working according to the desired specification and requirements.
Integration testing
After the unit testing all the modules are combined and tested at the same time. The purpose of this testing is to determine whether all the modules are interfacing with each other correctly or not. We have tested our system in integrated form which was also working correctly.
System testing
System testing is carried out whether the developed system is working according to the desired specification and requirement or not. The system is checked using the actual
49 Online Reservation System of Hotel White Palace
Chapter 9
system testing
data values. Also the reports and queries generated by the system are checked against the requirements.
8.2 Developed system testing All these testing strategies are adopted during the testing of the developed system the working of the system is almost perfect. The basic testing techniques are as follows 8.2.1 White- Box Testing: White-box testing strategy is actually applied to know the internal workings of a product. Tests are conducted to ensure that “Natural Medicine Information System” either works properly, that is, internal operation performs according to the specification and all internal components are adequately exercised. Following steps were conducted to perform white-box testing strategy.
All the independent paths within all the modules were exercised once or more during the time of development and after the development was completed.
All logical decisions on their “true” and “false” sides were exercised.
All loops at their boundaries and within their operational bounds were executed.
Exercising them one by one ensured the validity of all the internal data structures.
8.2.2 Black- Box Testing Black-box testing strategy is used to know the specified function that a product has been designed to perform. Tests are conducted to demonstrate that each function is fully operational at the same time errors in each function are searched. For the purpose of carrying out this testing strategy, we involved our end users to operate the software and check its functionality especially in terms of following considerations:
Is searching of the patient should be carried out by ID or Name.
Do you find it comfortable to retrieve the date about any product?
Do you feel it easy to edit, add new, refresh or save the data using forms?
Don’t you feel it easy to generate reports on the basis of different criteria?
Are you confronted to any problem in searching the Records? 50
Online Reservation System of Hotel White Palace
Chapter 9
system testing
Is the software is capable to provide correct record retrieve from database?
After this evaluation process, answers given by the end users helped us positively to uncover errors and drawbacks in the software, which were successfully removed in the “Debugging Phase”.
8.3 System Evaluation When the system is implemented successfully, the designer evaluates the system to see whether the objectives of the system are accomplished or not, also developed system is complete or not. There is always need for improvements. All exercise may achieve an immediate goal and arrive at a stage that logically seems an appropriate point for termination of given object. However, a point that appears to be a terminal point for one project may be a good beginning of another. So discussing features of the developed system and the future enhancements carries out evaluation of the system.
8.4 Merits of the System
Efficiency: The system is very efficient than the previous one because it performs all the tasks in lesser time and with no complexity at all.
Error Reduction: Errors are reduced in the newly designed system. A number of checks are implemented on fields where required, which help while entering the data. In this way most of the errors at entry time are reduced.
User Friendly: System is user friendly. The user feels easy while using the system. Interface of the system is very interactive. If the users enter wrong input, proper messages are displayed.
Security: The system works by providing a password. In this way it is secured. Unauthorized person cannot access data.
8.5 System conversion After the completion of the testing phase the process of conversion is performed. Conversion is the process of switching over the old system to new system. There are three different methods for the system conversion ensuring proper working of the system.
51 Online Reservation System of Hotel White Palace
Chapter 9 8.5.1
system testing Direct Approach
In this approach the old system is immediately replaced by the new developed system. This method requires the careful advanced planning. Failure of the new system will destroy the system. 8.5.2
Parallel approach
In this approach we run both the new and old system side by side. It means that user continuous to use the old system and simultaneously learn to operate the new system thus if any problem occur in using the new system, the organization can still fall back on the old system without loss of information. 8.5.3
Pilot Approach
In this method a working version of the system is implemented in one portion of the organization. The advantage of this method is that it provide sound basis for the whole system to install.
8.6
Developed System Conversion The most feasible conversion technique, in this case should be parallel conversion
approach. Although this implementation approach is more expensive and involve additional work load, the old system will be safe and the procedure followed for the some time until it is conformed that the newly designed is working satisfactorily.

CHAPTER 10
Database Access and Application Integration 9.1 Database Access and Application Integration This is the fastest-growing area of the Web. At first, as people were just getting accustomed to HTML and the Web, most sites featured fairly static HTML pages. Even if well designed, the ultimate effect was a very easy to use and splashy catalog with the ability to reference other sites. Database integration changes all of that. Databases allow the user to search through reams of data far too large to browse through manually, even in summary form. They allow for different views of the same data, creating and utilizing data relationships on the fly. And most importantly, by using "live" data on the Web, the site is always kept up-to-date, accurate, and interesting. The different uses for database interfaces on the Web are as complex and interesting as the Web itself. Customers visiting a well-wired retail site can easily check the status of their orders, browse through a customized list of inventory items, or request to be notified via e-mail when a product becomes available. A tourist planning a trip to a city may search for available suites at a resort, register online for activities that interest them, or download the menu - and the pages which later show the scenic points of the city are customized to the user's interests. The site is now much more useful than its equivalent paper counterpart, since it reflects the data on the site in a manner that is customized to each particular user. Just like we have applied a medium size database to allow the students to see their results on line and also the administrator can enter, update, delete student’s records. Students wanting to see their result in their homes do not want to retrieve documents that describe their result. 9.2 Control Flow and a Sample Application Because of the design of the Web, designing a database interface for the Web is different than traditional procedural or event-driven database applications. The program must be designed to work with pages; a database program is called when a form is
53 Online Reservation System for Hotel White Palace
Chapter 10 Database Access and Application Integration Submitted or a link is chosen, and must generate a new HTML page to be returned to the user. Gathering Query Information Execution of User's Query Adding a Record Modifying a Record
9.3 Effective Programming Techniques Following are a few programming hints that were applied that make our Web application easier to use and more effective. "Hidden" Input Fields Hidden fields can be a great benefit to the database designer. Hidden fields are fields that are included in HTML forms and are submitted with the rest of the user's data entry, but the user never sees them and cannot normally change the values. Administrator may use hidden fields to pass information along to later database programs that is not of interest to the user, such as the record IDs of the row being updated, deleted, inserted etc and so on. Use of POST and GET Submission Types When implementing an HTML Form, the form designer may choose whether the user's data will be submitted using the "GET" or "POST" methods. According to the HTML 2.0 specification, the "GET" method should be used when submitting the form has no side effects on the database (such as queries, or the start of an update), and the "POST" method should be used when submission will change the state of the database (such as add, update, or delete operations). Maintaining Security Implementing secure PHP programs is important since the programs can possibly alter data on the machine itself. However, with database programming, the problem is magnified greatly since the programs work directly with data that can be fairly easily corrupted if the programmer is not careful. An important thing to remember is that the user can alter any of the data on a form, even in ways not usually possible using a normal Web browser. For example, a radio button may be returned to the PHP script as a value that is not legal and never appeared in any of the choices to the user. A malicious user 54 Online Reservation System for Hotel White Palace
Chapter 10 Database Access and Application Integration may change the values of “hidden” fields at any time. Fields that has a length limitation that the browser normally enforces may be submitted with longer strings. As a database Programmer who is concerned about the integrity of the data, no one can assume that any of the data that comes from the user's browser will fit the constraints of the calling page. User Authentication The Web is rapidly advancing in its ability to have servers automatically recognize and verify which user is accessing an PHP program, but such automatic solutions to this problem are still too sparsely implemented to be able to be used in a generic environment. However, database programmers may still make use of password fields or HTML's almost-official browser authentication to verify users at the beginning of the application, and have the browser keep track of authentication credentials as the user moves through the application. User Preferences If a site already has users who are logging in or registering themselves, then one of the best things that a site can do is track their interests and preferences to customize the site for that user. This makes a site come "alive" and become more interesting and useful to all of the users, since they get information that is customized and appropriate for their interests. It also makes a site more memorable and more likely to be revisited and passed around through word-ofmouth, which is am important consideration for sites that are seeking popularity.
9.4 Browsers as Database Front Ends Creating a Web interface to a database may do more than just give users outside a company access to your information - it may also provide an easy, cross-platform solution for in-house use. Once a good, robust gateway is written between the Web and An existing database server, users can immediately have cross-platform access and update ability to that database by using their Web browser as a database client. Almost every hardware platform and operating system has a World Wide Web browser available, which eliminates the need for company’s MIS staff to worry about creating a client for Macintosh, Windows, and UNIX.

User Interface Design
CHAPTER 12
11.1 Introduction: It is particularly important first to design how the system will look and respond to user before designing the software structure. The most critical and creative aspect of development is to design the user interface. User interface design determines how the system will look for the user from outside. The basic design principles, considered during the user interface design, are the following.
