1.2 FEASIBILITY STUDY

A feasibility study focus on identifying and evaluating alternative candidate system with a recommendation of the best system for the income tax department.

The success of system depends largety on how accurately a program is defined, thoroughly investigated and properly carried out through the choice of solution. Emphasis should be on the logical requirement. Not until the problem has been identified, defined and evaluated should the analyst think about the solutions and whether the problem is worth solving.

This step is intended to help the customer, staff and the analyst understand the real problem rather than its symptoms.There are several reasons why it is difficult to determine customer, management requirements.

Firstl Firstly, y, system system requir requireme ement nt change change and custome customer, r, manage managemen mentt requir requireme ements nts must must be modified. Secondly, the articulation of requirement is very difficult. Functions and processes are not easily described.

Reinforcement of their work is usually not realized until the implementation phase and lastly the pattern pattern of intera interactio ction n betwee between n manage managemen mentt and analys analysts ts in designi designing ng inform informati ation on requirements is complex.

Management and analyst traditionally do not share a common orientation toward problem definition. For example, example, in the analyst view, view, the problem definition must be translatable into a system system design design express expressed ed quanti quantitat tative ively ly in terms terms of output output,, input, input, process processes es and data data structures.

 Approximate time, effort and cost estimates for completion of the

 project.

There are three aspects in the feasibility study.

1.2.1 TECHNICAL FEASIBILITY This is concern with specifying equipment and software that will successfully satisfy the custo custome merr and and mana manage geme ment nt requi require reme ment nt.. The The tech techni nical cal need need of the the syst system em may may vary vary considerably, but might include :

 The facility to produce output in given time.  Response time under certain conditions.

 Ability to process a certain volume of transaction at a particular speed.

 Facility to communicate data to distant location.

In examining technical feasibility, configuration of the system is given more importance than the actual make of hardware. The configuration should give a complete picture about the system system requir requireme ements nts.. What What speed speed of input input and output output should should be achiev achieved ed at partic particula ular  r  quality of printing. This can be used as a basis for the tender document against which dealers

and manufacturers can later make their equipment bids. Specific hardware and software can then be evaluated keeping in view with the logical needs.

At the feasibility stage, it is desirable that two or three different configuration will be  pursued that satisfy the key technical requirements but which present different levels of  ambition and cost. Investigation of these technical alternatives can be aided by approaching a range of suppliers for preliminary discussion. Out of all type of feasibility, technical feasibility generally is the most difficult to determine.

1.2.2 OPERATIONAL FEASIBILITY

It is main mainly ly relat related ed to huma human n orga organi nizat zatio ional nal and and poli politi tical cal aspe aspect cts. s. The The poin points ts to be considered are:

 What changes will be brought with the system?  What organizational structures will get effected?

 What new skills will be required? Do the existing staff members have

these skills? If not, can they be trained in due course of time?

Generally project will not be rejected simply because of operational infeasibility but such cons consid ider erat atio ions ns are are like likely ly to crit critic ical ally ly affe affect ct the the natu nature re and and scop scopee of the the even eventu tual al recomm recommend endatio ations. ns. A small small group group who are famili familiar ar with with inform informati ation on system system techni technique quess which understand the part of the business that are relevant to the project and are skilled in system and design process carries out this feasibility study.

1.2.3 ECONOMIC FEASIBILITY

Economic feasibility concerns returns from investments in a project. It determines whether it is worthwhile to invest the money in the proposed project or whether something else should  be done with it. It is not worthwhile spending a lot of money on a project for no returns, especially if there are many other things, which could be done with that money.

To ensure that the new project will certainly lead to benefits outweighing the cost, Cost Benefit Analysis is carried carried out. out. In cost cost benefit benefit analysi analysis, s, variou variouss benefi benefits ts and the cost cost

2.3 INTRODUCTION TO ASP.NET This proposed software is going to be developed using the latest technology from Microsoft called Microsoft. NET and it is the software that connects information, people, systems, and devices. It spans clients, servers, and developer tools, and consists of:

7

The .NET Framework 3.5, used for building and running all kinds of software, including Web-based applications, smart client applications, and XML Web services—components that facilitate integration by sharing data and functionality over a network through standard,  platform-independent protocols such as XML (Extensible Markup Language), SOAP, and HTTP .

2.4 ADVANTAGES OF .NET Developer tools, such as Microsoft Visual Studio.NET 2008, which provides an integrated develo developm pment ent enviro environme nment nt (IDE) (IDE) for maximi maximizing zing develo developer per produc productiv tivity ity with with the .NET .NET Framework. A set of servers, including including Microsoft Windows Server 2008, Microsoft SQL Server, Server, that integrates, runs, operates, and manages Web services and Web-based applications. The .NET Framework offers a number of advantages to developers. The following paragraphs describe them in detail.

2.4.1 CONSISTENT PROGRAMMING MODEL Different programming languages have different approaches for doing a task. For example, accessing data with a VB 6.0 application and a VC++ application is totally different. When using different programming languages to do a task, a disparity exists among the approach developers developers use to perform perform the task. The difference in techniques techniques comes from how different different langua languages ges intera interact ct with with the underl underlyin ying g system system that that applica applicatio tions ns rely rely on.Wit on.With h .NET, .NET, for  example, accessing data with a VB .NET and a C# .NET looks very similar apart from slight syntactical differences. Both the programs need to import the System. Data namespace, both the programs establish a connection with the database and both the programs run a query and

8

display the data on a data grid. The VB 6.0 and VC++ example mentioned in the first  paragraph explains that there is more than one way to do a particular task within the same language. The .NET example explains that there's a unified means of accomplishing the same task by using the .NET Class Library, a key component of the .NET Framework. The functionality that the .NET Class Library provides is available to all .NET languages resulting in a consistent object model regardless of the programming language the developer  uses.

2.4.2 DIRECT SUPPORT FOR SECURITY Developing an application that resides on a local machine and uses local resources is easy. In this scenario, security isn't an issue as all the resources are available and accessed locally. locally. Consider Consider an application application that accesses data on a remote remote machine or has to perform perform a  privileged task on behalf of a nonprivileged user. In this scenario security is much more important as the application is accessing data from a remote machine. With .NET, the Framework enables the developer and the system administrator to specify method level security. It uses industry-standard protocols such as TCP/IP, XML, SOAP and HTTP HTTP to facil facilit itate ate dist distrib ribut uted ed appl applic icati ation on comm commun unic icati ation ons. s. This This make makess dist distri ribu buted ted computing more secure because .NET developers cooperate with network security devices instead of working around their security limitations.

2.4.3 SIMPLIFIED DEVELOPMENT EFFORTS Let's take a look at this with Web applications. With classic ASP, when a developer needs to  present data from a database in a Web page, he is required to write the application logic (code) and presentation logic (design) in the same file. He was required to mix the ASP code with the HTML code to get the desired result.

9

ASP.NET and the .NET Framework simplify development by separating the application logic and presentation logic making it easier to maintain the code. You write the design code (presentation logic) and the actual code (application logic) separately eliminating the need to mix HTML code with ASP code. ASP.NET can also handle the details of maintaining the state of the controls, such as contents in a textbox, between calls to the same ASP.NET page. Another advantage of creating applications is debugging. Visual Studio .NET and other third party  providers provide several debugging tools that simplify application development. The .NET Framework simplifies debugging with support for Runtime diagnostics. Runtime diagnostics helps you to track down bugs and also als o helps you to determine how well an application performs. The .NET Framework provides three types of Runtime diagnostics: Event Logging, Performance Counters and tracing.

2.4.4 EASY APPLICATION DEPLOYMENT AND MAINTENANCE The .NET Framework makes it easy to deploy applications. In the most common form, to install an application, all you need to do is copy the application along with the components it requires into a directory on the target computer. The .NET Framework handles the details of  locating and loading the components an application needs, even if several versions of the the targ target et comp comput uter er.. The The .NET .NET Fram Framew ewor ork k ensu ensure ress that that all all the the same same applica applicatio tion n exist exist on the components the application depends on are available on the computer before the application begins to execute.

2.5 .NET FRAMEWORK  The Microsoft .NET Framework is a software component that can be added to or is included with with the Microso Microsoft ft Window Windowss operati operating ng system system.. It provid provides es a large large body body of pre-co pre-coded ded solutions to common program requirements, and manages the execution of programs written specifically for the framework. The .NET Framework is a key Microsoft offering, and is intended to be used by most new applications created for the Windows platform.

10

The pre-coded solutions that form the framework's class library cover a large range of   programming needs in areas including: user interface, data access, database connectivity, cryp crypto togr grap aphy hy,,

communications. The functions of the class library are used by programmers who combine them with their own code to produce applications. Programs written for the .NET Framework execute in a software environment that manages the program's runtime requirements. This runtime environment, which is also a part of the .NET Framework, is known as the Common Language Runtime (CLR). The CLR provides the appearance of an application virtual machine, so that programmers need not consider the capabilities of the specific CPU that will execute the program. The CLR also provides other  import important ant service servicess such such as security security mechan mechanism isms, s, memory memory manage managemen ment, t, and except exception ion handling. The class library and the CLR together compose the .NET Framework. The framework is intended to make it easier to develop computer applications and to reduce the vulnerability of applications and computers to security threats. First released in 2002, it is included with Windows XP SP2, Windows Server 2003 and Windows Vista, and can be installed on most older versions of Windows. Microsoft .NET Framework was designed with several intentions:

• Intero Interoper perabi ability lity - Becaus Becausee interac interactio tion n betwee between n new and older older applica applicatio tions ns is commonly required, the .NET Framework provides means to access functionality that is implem implemente ented d in progra programs ms that that execut executee outsid outsidee the .NET .NET enviro environme nment. nt.

A design goal of the .NET Framework was to support platform independence[citation needed]. That is, a program written to use the framework should run without change on any type of computer for which the framework is implemented. However, Microsoft has only implemented the full .NET framework on the Windows operating system. Microsoft and others have implemented portions of the framework on non-Windows systems, but to date these implementation implementationss are neither complete complete nor widely used, so full cross-platform cross-platform support has not been achieved.

2.7 SOFTWARE FEATUERS 2.7.1 LANGUAGES USED: C#

Visual C# .Net is designed to be a fast and easy way to create .NET applications, including Web services and ASP.NET Web applications. Applications written in Visual C# are built on the services of the common language runtime and take full advantage of the .NET Framework.It is a simple, elegant, type-safe, object-oriented language recently developed by Microsoft for building a wide range of applications. Anyone familiar with C and similar  lang langua uage gess will will find find few few prob proble lems ms in adap adapti ting ng to C#. C#. C# is desig designe ned d to brin bring g rapid rapid development to the C++ programmer without sacrificing the power and control that are a hallmark of C and C++. Because of this heritage, C# has a high degree of fidelity with C and C++, and developers familiar with these languages can quickly become productive in C#. C#  provides intrinsic code trust mechanisms for a high level of security, garbage collection, and type safety. C# supports single inheritance and creates Microsoft intermediate language (MSIL) as input to native code compilers.It is fully integrated with the .NET Framework and the common language runtime, which together provide language interoperability, garbage collection, enhanced security, and improved versioning support. C# simplifies and modernizes some of the more comple complex x aspect aspectss of C and C++, C++, notabl notably y namesp namespace aces, s, classes classes,en ,enume umerat ration ions, s, overlo overloadi ading, ng, and structured exception handling. C# also eliminates C and C++ features such as macros, multiple inheritance, and virtual base classes. For current C++ developers, C# provides a powerful, high-productivity language alternative. Visual C# provides prototypes of some s ome common project types, including:

2.7.2 HTML HTML (Hyper Text Mark up Language) is the language that is used to prepare documents for online publications. HTML documents are also called Web documents, and each HTML document is known as Web page. A page is what is seen in the browser at any time. Each Web site, whether on the Internet or Intranet, is composed of multiple pages. And it is  possible to switch among them by following hyperlinks. The collection of HTML pages makes up the World Wide Web. A web web page pagess is basic basical ally ly a text text file file that that cont contai ains ns the the text text to be disp displa laye yed d and and references of elements such as images, sounds and of course hyperlinks to other documents. HTML pages can be created using simple text editor such as Notepad or a WYSIWYG application such as Microsoft FrontPage.In either case the result is a plain text file that computers can easily exchange. The browser displays this text file on the client computer. "Hypertext" is the jumping frog portion. A hyperlink can jump to any place within your own  page(s) or literally to anyplace in the world with a 'net address (URL, or Uniform Resource Locator.) It's a small part of the html language.

2.8 INTERNET INFORMATION SERVER (IIS): A web web serv server er is a prog program ram conn connect ected ed to the the World World Wide Wide We Web b (www (www)) that that furn furnish ishes es resources from the web browser. Microsoft IIS is a web server integrated with Windows.NET server that makes it easy to  publish information and bring business application to the web. Because of its tight inte integr grat atio ion n with with Wind Window owss NT serve server, r, IIS IIS guar guaran ante tees es the the netw networ ork k admi admini nistr strat ator or and and application application developer developer the same security, Networking and administrato administratorr functionali functionality ty as windows NT server. Above and beyond its use of familiar Windows NT server  Tools and functionality, IIS also has built-in capabilities to help administer secure websites, and to develop server-intensive web application.

2.8.1 FEATURES OF IIS: IIS prov provid ides es inte integr grat ated ed secur securit ity y and and acces accesss to a wide wide rang rangee of cont conten ent, t, work  work  seamlessly with COM components, and has a graphical interface-the Microsoft Management Console (MMC) –that you can use to create and manage your ASP application. 2.8.1.1 IIS PROVIDES INTEGRATED SECURITY:

On the the inter interne net, t, most most site sitess allo allow w anyb anybod ody y to conn connect ect to the the site site.. The The exce except ptio ions ns are are commercialists where you pay a one time, monthly fee to access the site. Sites that are restrict the access called secured site. Secured site use either integrated security or login,  password security. IIS support both of these methods. methods. 2.8.1.2 IIS PROVIDES ACCESS TO CONTENT:

All web servers can deliver HTML files, but they differ widely in how they treat other types of content. Most servers let you add and modify Multi-purpose Internet Mail Extensions (MMIE) types, but integrate directly into the windows registry. That means IIS natively

16

understands how to treat most common windows file format, such as text (TXT) files, appl2.ication initialization (INI) files, executable (EXE) files and many others 2.8.1.3 IIS PROVIDES AN INTERFACE FOR COM

These objects are accessible from ASP and othe otherr langu languag ages es.. That That mean meanss you you can can adju adjust st serve serverr conf config igur urati ation on and and creat createe virtu virtual al directories and webs programmatically. IIS 4 and higher store settings and web information in a spoil database called the Metaphase. You can use the IIS Admin objects to create new sites and virtual directories be alter the properties of existing sites and virtual directories 2.8.2 IIS ARCHITECTURES OVERVIEW:

IIS is a core product, which means that it is designed to work closely with many other   products, including all products in the Windows NT Server 4.0 Option pack. The following figure figure shows shows the relati relations onship hip between between IIS and other produc products ts instal installed led as part part of the Windows NT Server 4.0 Option pack. 2.8.3 SECURITY FOR IIS APPLICATION

2.8.5 IIS WEBSITE ADMINISTRATION

Admini Administer stering ing website websitess can be time time consum consuming ing and costly, costly, especia especially lly for people people who manage large internet Service Provider (ISP) Installations. To save time and money Sip’s support only large company web siesta the expense of personal websites. But is there a costeffective way to support both? The answer is yes; if you can automate administrative tasks and let users administer their own sites from remote computers. This solution reduces the amount of time and money it takes to manually administer a large installation, without reducing the number of web sites supported. Microsoft Internet Information server (IIS) version 4.0 offers technologies to do this: 1. Windows scripting Host (WSH) (WSH) 2. IIS IIS Admi Admin n obje object ctss buil builtt on top top of Acti Active ve Dire Direct ctor ory y serv servic icee Inte Interf rfac ace( e(AD ADS) S)))

With these technologies working together behind the scenes, the person can administers sites from the command line of central computer and can group frequently used commands in batch files.Then all user need to do is run batch files to add new accounts, change  permissions, add a virtual server to a site and many other tasks.

 SYSTEM DESING & ANALYSIS  4.1 SYSTEM DESIGN System design is the solution to the creation of a new system. This phase is composed of  severa severall system systems. s. This This phase phase focuse focusess on the detail detailed ed implem implement entati ation on of the feasib feasible le system system.. It emphasis emphasis on translating translating design specifications specifications to performance performance specification. specification. System design has two  phases of development logical and physical physical design. During logical design phase the analyst describes inputs (sources), out puts (destinations), databases (data sores) and procedures (data flows) all in a format that meats the uses requirements. The analyst also specifies the user needs and at a level that virtually determines the information flow into and out of the system and the data resources. Here the logical design is done through data flow diagrams and database design. The physical design is followed by physical design or coding. Physical design produces the working system by defining the design specifications, which tell the programmers exactly what the candidate system must do.

The programmers write the necessary programs that accept input from the user, perform necessary processing on accepted data through call and produce the required report on a hard copy or display it on the screen .

4.1.1 LOGICAL DESIGN Logical design of an information system shows the major features and also how they are related to one another. The first step of the system design is to design logical design elements. This is the most creative and challenging phase and important too. Design of   proposed system produces the details of the state how the system will meet the requirements identified during the system analysis that is, in the design phase we have to find how to solve the difficulties faced by the existing system. The logical design of the proposed system

23

should should includ includee the detail detailss that that contai contain n how how the soluti solution onss can be implem implement ented. ed. It also specifies how the database is to be built for storing and retrieving data, what kind of reports are to be created and what are the inputs to be given to the system. The logical design includes input design, output design, and database design and physical design

4.1.2 INPUT DESIGN Input design is the link between the information system and the user. It comprises the developing specification and procedures for data preparation and those steps are necessary to put transaction data into a usable form for processing data entry. The activity of putting data into the computer for processing can be achieved by inspecting the computer to read data from a written or   printed document or it can occur by having people keying the data directly into the system. The design of input focuses on controlling the amount of input required, controlling errors, avoiding delay, avoiding extra steps and keeping the process simple. The system needs the data regarding the asset items, depreciation rates, asset transfer, physical verification for various validation, checking, calculation and report generation.. The error raising method is also included in the software, which helps to raise error message while wrong entry of  input is done. So in input design the following things are considered. What data should be given as input?

•

How the data should be arranged or coded?

•

The dialogue to guide the operating personnel in providing input.

•

Methods for preparing input validations and steps to follow when error occur

4.1.3 OUTPUT DESIGN

24

Computer output is the most important and direct information source to the user. Output design is a process that involves designing necessary outputs in the form of reports that should be given to the users according to the requirements. Efficient, intelligible output design design should improve the system's system's relationshi relationship p with the user and help in decision decision making. Since the reports are directing referred by the management for taking decisions and to draw conclusions they must be designed with almost care and the details in the reports must be simple, descriptive and clear to the user. So while designing output the following things are to be considered. •

Determine what information to present

•

Arra Arrang ngee the the pre prese sent ntat atio ion n of of inf infor orma mati tion on in an acce accept ptab able le form format at

•

Deci Decide de how how to to dis distr trib ibu ute the the ou outpu tput to to in intend tended ed rece receip ipts ts

Depending on the nature and future use of output required, they can be displayed on the monitor for immediate need and for obtaining the hardcopy. The options for the output reports are given in the appendix .

4.1.4 PHYSICAL DESIGN The process of developing the program software is referred to as physical design. We have to design the process by identifying reports and the other outputs the system will  produce. Coding the program for each module with its logic is performed in this s tep. Proper  software specification is also done in this step.

4.1.5 MODULAR DESIGN

25

A software system is always divided into several sub systems that makes it easier for the development. A software system that is structured into several subsystems makes it easy for  the development and testing. The different subsystems are known as the modules and the  process of dividing an entire system into subsystems is known as modularization or  decomposition.

A system cannot be decomposed into several subsystems in any way. There must some logical barrier, which facilitates the separation of each module. The separation must be simple but yet must be effective so that the development is not affected. The The syst system em unde underr cons consid ider erat atio ion n has has been been divi divide ded d into into seve severa rall modu module less taki taking ng in consideration the above-mentioned criteria. The different modules are ❖ ADMINISTRATOR  ❖ EMPLOYEE ❖ PAN CARD ❖ EMPLOYEE DETAIL ❖ INCOME TAX

4.1.6 DATABASE DESIGN

The overall objective in the development of database technology has been to treat data as an organizational resource and as an integrated whole. DBMS allow data to be

26

 protected and organized separately from other res ources. Database is an integrated collection c ollection of data. The most significant form of data as seen by the programmers is data as stored on the direct access storage devices. This is the difference between logical and physical data.

Data Databa base se files files are are the the key key sour source ce of info inform rmat atio ion n into into the the syste system. m. It is the the proc proces esss of  designing database files, which are the key source of information to the system. The files should be properly designed and planned for collection, accumulation, editing and retrieving the required information.

The organization of data in database aims to achieve three major objectives: -

•

Data integration.

•

Data integrity.

•

Data independence.

The The prop propos osed ed syst system em stor stores es the the info inform rmat atio ion n relev relevan antt for for proc process essin ing g in the the MS SQL SQL SERVER database. This database contains tables, where each table corresponds to one  particular type of information. Each piece of information in table is called a field or column. A table also contains records, which is a set of fields. All records in a table have the same set of fields with different information.

There are primary key fields that uniquely identify a record in a table. There are also fields that contain primary key from another table called foreign keys.

4.1.6.1 NORMALIZATION

 Normalization is a technique of separating redundant r edundant fields and braking up a large table in to a smaller one. It is also used to avoid insertion, deletion and updating anomalies. All the

27

tables have been normalized up to the third normal form. In short the rules for each of the three normal forms are as below.

•FIRST NORMAL FORM

A relation is said to be in 1NF if all the under lying domain of attributes contain simple individual values. •SECOND NORMAL FORM

The 2NF is based on the concept of full functional dependency. A relation said to be in 2NF if and only if it is in 1NF and every non-key attribute is fully functionally dependent on candidate key of the table.

•THIRD NORMAL FORM

The 3NF is based on the concept of transitive dependency. A relation in 2NF is said to be in 3NF if every non-key attribute is non-transitively

4.2 DATA FLOW DIAGRAM Graphical description of a system data and how the process the data is known as data flow diagram. Data flow diagram is a graphical tool which is used to describe and analysis the movement of the data through a system. It does not supply detail description (how) of  module moduless but (what) (what) and (from (from where) and (to where) where) of each and every every module module of the organization. The system under consideration may be manual or automated. In the data flow diagram there are four symbols to develop the system, which are :Arrows or dataflow:- It shows the direction in which particular data is moving e.g.

Circle or bubble process:- It represent a process that transforms incoming dataflow (s) into

outgoing dataflow (s) e.g.

Boxes or data store: - The destination where the processed input data is to be stored is

known as the data store e.g.

Square or external entities: - The entities which are not the part of the system organization

e.g.

31

Physical dataflow diagram: - Based on currently existing system or it is a graphical model

of current system. Comprises of the following •

Content diagram.

•

First level dataflow diagram.

•

Second level dataflow diagram.

Logical dataflow diagram: - this is based on the requirement of the currently existing

system or it represents the newly proposed system. There are seven rules govern construction data flow diagram:•

Arrows should not cross each other.

•

Squares, circles and file must bear names.

•

Decomposed data flow must be balance.

•

Squares and circle can have the same name.

•

Draw all data flows around the outside of the diagram.

•

Choose the meaningful names of data flows, processes and data store. Use strong verb followed by nouns.

Control information such as record counts, password and validation requirements are not  pertinent to a data flow diagram.

4.3 UNIFIED MODELING LANGUAGE ( UML UM L DIAGRAMS) UML stands for Unified Modeling Language. It is a third generation method method for specif specifyin ying, g, visual visualizin izing g and docume documenti nting ng the artifac artifacts ts of an object object orient oriented ed system under development. Object modeling is the process by which the logical objects in the real world (problem space) are represented (mapped) by the actual objects in the program (logical or a mini world). This visual representation of the objects, their relationships and their structures is for the ease of understanding. This is a step while developing any product after analysis. The goal from this is to produce produce a model of the entities involved involved in the project which later  need to be built. The representations of the entities that are to be used in the product being developed developed need to be designed designed.. Software Software design is a process that that gradually gradually changes as various new, better and more complete methods with a broader understanding of the whole  problem in general come into existence.

Use Case Diagrams: Use case diagram consists of use cases and actors and shows the interaction between them. The key points are: •

The main purpose is to show the interaction between the use cases and the actor.

•

To represent the system requirement from user’s perspective.

•

The use cases are the functions that are to be performed in the module.

•

An actor could be the end-user of the system or an external system.

CHAPTER-5

TESTING  Software testing is one element of a broader topic that is often referred to as verification and valida validatio tion n (V&V). (V&V). Verifi Verificati cation on refers refers to the set of activit activities ies that that ensure ensure that that softwar softwaree correctly implements a specific function. Validation refers to a different set of activities that ensures that the software that has been built is traceable to customer requirements.

5.1 A SOFTWARE TESTING STRATEGY: A strategy for software testing may be viewed as a spiral model. model. Unit Testing begins at the vertex of the spiral and concentrates on each unit of the software as implemented in the source code. Testing progresses by moving outward on the spiral to integration of testing, where the focus is on design and the construction of the software architecture. Taking another turn outward on the spiral, we encounter validation testing, where requirements establ establish ished ed as the part part of the softwa software re requir requireme ements nts analys analysis is are valida validated ted agains againstt the software software that has been constructed. constructed. Finally, Finally, we arrive at system testing, testing, where the software and other system elements are tested as a whole.

37

Testing within the context of software engineering is actually a series of four steps that are implemented sequentially. Initially, test focus on each module individually, assuring that it functions properly as a unit. Hence, the name Unit testing. Unit testing makes heavy use of  white-box testing techniques, exercising specific path in a module’s control structure to ensure complete coverage and maximum error detection. Next, modules must be assembled or integrated to from the complete software package. Integration testing addresses the issues associated associated with the dual problems problems of verification verification and program program construction. construction. Black-box Black-box test case design techniques are the most prevalent during integration, although a limited amount of white-box testing may be used to ensure coverage of major control paths. After the softwa software re has been been integr integrated ated,, a set of high-o high-orde rderr tests tests is conduc conducted ted.. Valida Validatio tion n testing testing  provides final assurance that the software meets all functional, f unctional, behavioral, and performance requirements. Black-box testing techniques are used exclusively during validation. The last high-order testing step falls outside the boundary of software engineering and into the broader contest of computer system engineering. Software, once validated, must be combined with other system elements (e.g., hardware, people, and database). System testing verifies that all elements mesh properly and that overall system function/performance is achieved.

5.2 TESTING DOCUMENTATION The goal of testing is to locate system errors before installation these system errors can take different forms including the coding errors that reduce system efficiency. For this reason our  team project members designed a systematic testing procedure that covers all functions, even the ones that are certain to work. The following are the testing approaches used by the team:

5.2 1 BLACK BOX TESTING 5.2.2 WHITE WHITE BOX TESTING TESTING

38

5.2.3 USER INTERFAC INTERFACE E TESTING 5.2.4 USE SCENARIO SCENARIO TESTING TESTING 5.2.5 SECURITY TESTING 5.2.1 BLACK BOX TESTING The test was based on checking the requirements stated on the system request in the first milestone of the project. The team crosschecked the fully developed product with functionality stated in the system request document and is proud to announce that it has completed all the promised features (except the few mentioned and discussed with the client  by the members of the team).The products developed include the four different bank  accounts equipped with update and add features for each one of them. The team has also ensured a secure login with user name and password features .The tests conducted by the team members on the functionality of the products were successful.

5.2.2 WHITE BOX TESTING The code for the interactive products is coded in visual-basic The programmers of the  project team added comments to the processes performed by the system. This is done for  future readability and a guide line for the code. The coding for the interface follows the formal coding standard and has been reviewed by the members of the team. The system analyst and the programmers have conducted several sessions of “code walk-through” to avoid errors. Thus the team is proud to say this part of program testing was completed successfully.

5.2.3 USER INTERFACE TESTING The user interface testing includes the following subcategories identified by the team: 3.1 The three click rule testing 3.2 The two click rule testing

39

3.3 Loading time testing 3.4 Query time testing 3.5 Query results testing 3.6 Product Headings 3.7 Aesthetics /consistency testing 3.8 Format Testing 3.9 User experience testing

5.2.4 USE SCENARIO TESTING The use scenario testing includes the following subcategories defined by the team: 4.1 Testing results for appropriate data 4.2 Testing results for different data format 4.3 Testing results for inappropriate data 4.4 Testing results for unfilled data fields 4.5 Testing links for different areas.

5.2.5 SECURITY TESTING The security testing for the team involved the following: 5.1 login /password security.
