INTRODUCTION Real estate is "Property consisting of land and the buildings on it, along with its natural resources such as crops, minerals, or water; immovable property of this nature; an interest vested in this; (also) an item of real property; (more generally) buildings or housing in general. Also: the business of real estate; the profession of buying, selling, or renting land, buildings or housing." The Real Estate Web Application is developed focusing on the aim to make a good web application that can make this profession of buying, selling, or renting land, buildings or housing easy and accessible to everyone who are interested. Individuals, agents and developers are the key players here. Individual is a single person who is willing to buy/sell property. Whereas agent is interested in buying and selling but being a company working as a middle-man it can only book the property for buyers and sellers. The developer is again a company whose profession is to only construct buildings and sell them. The Real Estate Web Application provides the individual ability to register to this application and list properties, manage their accounts and also post requirements. Each candidate will have their own account with their own home page, from where they can contact agents, developers for buying or selling properties. On the other hand agents that are willing to publish the property listings for their company, can register and get their own account created and can list properties, contact callers and developers and book the property for interested buyers and sellers. Registered developers can list their properties and contact interested agents and individuals when required. From their homepage like others the builder can also use the advertise tab to promote his company. Interacting with the callers the developers can sell their property or allow the agents to book them against any buyer. The main stakeholders of this system are: 1. Admin. 2. Individual. 3. Agent. 4. Developer. Purpose The Real Estate Web Application is an interactive, effective and revenue-generating website designed for the Real Estate Industry. The main purpose of this application is to help the Real Estate Company to display unlimited number of property listings on the website. This application is an effort to provide such a web interface with some attractive and innovative features using the latest technologies. Scope The Scope of the Real Estate Web Application includes the following key points: 1. It should contain all the information about Individual, agent and developer while creating account. 2. It should contain all the information of the listed property and posted requirement.

3|Page

3. It should contain all details of the interested buyers and sellers along with the finally allotted list. 4. It should process the match of details for effective searching. 5. It should have Administrator for managing administrative work of site.

OBJECTIVE The purpose of creating this Real Estate Web Application is to outcast the discrepancies in hundreds of such existing systems on the World Wide Web. One of the basic problems with the existing systems is the non-interactive environment they provide to the users. Most of the applications involved in Real Estate business use some web template to put the content specific to their company and make it communicate with the database to search the listings. These templates simply use basic web controls to do this task making the web page non-interactive. On the other hand, the motive of this Real Estate Web Application is to allow the user to play with the search tool and create different combinatorial search criterion to perform exhaustive search. This system automates the manual real estate professional problem. We believe that once the organization chooses to use this system, it will eventually recognize the value and necessity of this system and understand the problems involved in the manual process. The foremost objective of this project is to give a different visualization styles to the Real Estate Website which has more features, attractive animations and all together a new look in contrast to the already existing websites. The main objective of this application is to help the Real Estate Company to display unlimited number of property listings on the website.

REQUIREMENT ANALYSIS Analysis is defined as the procedure by which we break down an intellectual or substantial whole into parts so that we can achieve our end goals. The development of a computer-based information system includes a systems analysis phase which produces or enhances the data model which itself is a precursor to creating or enhancing a database. There are a number of different approaches to system analysis. When a computer-based information system is developed, analysis would constitute the following steps: 1. The development of a feasibility study, involving determining whether a project is economically, socially, technologically and organizationally feasible. 2. Conducting fact-finding measures, designed to ascertain the requirements of the system's end-users. These typically span interviews, questionnaires, or visual observations of work on the existing system. 3. Gauging how the end-users would operate the system (in terms of general experience in using computer hardware or software), what the system would be used for etc.

Aim

The scope of this project “Real Estate Web Application” is to enable the buyers to search for property listings online. The motive of developing this application is to design a feature rich search engine which can make the search of commercial land/properties an easy task.

Goal

Goal is to gain a good knowledge of the complete life cycle of the project development starting from the Requirement Gathering Phase to the Testing Phase. The implementation of this application also gives a hands-on experience in JSP, SERVLET programming and also design efficient databases in Oracle.

Technologies

The main domain of this project is J2EE (Java 2 Enterprise Edition). Along with this the other technologies used are as follows: 1. Web Interface: HTML (Hyper Text Markup Language), CSS (Cascading Style Sheet), JavaScript 2. Database: SQL (Structured Query Language) 3. Web Applications: JDBC (Java Database Connectivity), Servlet, JSP (Java Server Page) J2EE J2EE stands for Java 2 Platform, Enterprise Edition. Its significance will become clear once we trace its lineage. First of all, Java is a programming language developed by Sun Microsystems, one of the giants of the industry. The Java Platform is a virtual machine, a processor look-alike that translates computerized instructions into functions. The Java language is such that it allows cross-platform communication between multiple kinds of devices. This portability is described by the Sun acronym WORA, which stands for "Write once, run anywhere." The 2 in the acronym J2EE stands for Version 2. As with many software applications, J2EE is Java Platform Version 2. Actually, the number 2 is often dropped nowadays, so J2EE becomes Java EE. Traditionally, though, it's still J2EE. HTML HTML (Hyper Text Markup Language): A markup language used to structure text and multimedia documents and to set up hypertext links between documents, used extensively on the World Wide Web. HTML is a display language, not a programming language. HTML is a markup language (the ML in HTML) that uses a fixed set of markup tags.

6|Page

HTML itself is the set of customizable “markup” tags that are inserted into HTML document govern its format, multimedia content, and hyperlinks. Any HTML viewer can display such documents but they are normally viewed using a Web browser. HTML is a programming language in that an HTML document is a program that, when “run” by a browser, displays its text as hypermedia (multimedia with hyperlinks). The “language” HTML is really only a collection of predefined tags which , when inserted into regular text, tell a web browser how to: a. Format the document and its text. b. Incorporate i.e. insert a graphic image, video sequence, or sound clip into the displayed document. c. Link into other locations, in the same document, in another web page, or even on another computer (Server), or d. Link to other programs written in Java, JavaScript or other languages (called CGI applications). Features of HTML:HTML stands for Hyper Text Markup Language. · An HTML file is a text file containing small markup tags. · The markup tag tells the Web browser how to display the page. · An HTML file must have an html or html file extension. · An HTML file can be created using a simple text editor. · It’s a display-only technology. CSS 1. CSS stands for Cascading Style Sheets. 2. Styles define how to display HTML elements. 3. Styles are normally stored in Style Sheets. 4. Styles were added to HTML 4.0 to solve a problem. 5. External Style Sheets can save you a lot of work. 6. External Style Sheets are stored in CSS files. 7. Multiple style definitions will cascade into one. 8. CSS provides means to customize inbuilt HTML tags. JAVASCRIPT JavaScript is a compact, object-based scripting language. It can provide interactive web pages, validate from data, and make your web page clearer. JavaScript is a lightweight interpreted scripting language. The language is most well-known for its use in websites. It was originally developed by Brendan Each of Netscape Communications. It adds interactive functions to HTML pages, which are otherwise static. JavaScript is easier to use than Java, but not as powerful and deals mainly with the elements on the Web page. On the client, JavaScript is maintained as source code embedded into an HTML page. On the Server, it is compiled into byte code (intermediate language), similar to Java programs. Features of JavaScript:· JavaScript was designed to add interactively to HTML pages. · JavaScript is a scripting language-a scripting language is a lightweight programming language. · A JavaScript is usually embedded directly in HTML pages. · A JavaScript is an interpreted language (means that script execute without preliminary compilation). · All major browsers, like Netscape and Internet Explorer, support JavaScript. SQL Structured Query Language (SQL) is a specialized language for updating, deleting, and requesting information from databases. SQL is an ANSI and ISO standard, and is the de facto standard database query language. A variety of established database products support SQL, 7|Page

including products from Oracle and Microsoft SQL Server. It is widely used in both industry and academia, often for enormous, complex databases. In a distributed database system, a program often referred to as the database's "back end" runs constantly on a server, interpreting data files on the server as a standard relational database. Programs on client computers allow users to manipulate that data, using tables, columns, rows, and fields. To do this, client programs send SQL statements to the server. The server then processes these statements and returns replies to the client program. JDBC JDBC stands for "Java DataBase Connectivity". It is an API (Application Programming Interface) which consists of a set of Java classes, interfaces and exceptions and a specification to which both JDBC driver vendors and JDBC developers adhere when developing applications. JDBC is a very popular data access standard. RDBMS (Relational Database Management Systems) or third-party vendors develop drivers which adhere to the JDBC specification. Other developers use these drivers to develop applications which access those databases. The JDBC API is a Java API that can access any kind of tabular data, especially data stored in a Relational Database. JDBC helps you to write java applications that manage these programming activities: 1. Connect to a data source, like a database. 2. Send queries and update statements to the database. Connectivity using JDBC. There are four kinds of drivers available in JDBC:1. JDBC ODBC Bridge Driver. 2. Partly Java Driver. 3. Pure Java Driver. 4. Native Driver. Servlet Servlets are Java technology’s answer to Common Gateway Interface (CGI) programming. They are programs that run on a Web server, acting as middle layer between a requests coming from a Web browser or other HTTP client and databases or applications on the HTTP server. Their job is to: 1. Read any data sent by the user. 2. Look up any other information about the request that is embedded in the HTTP request. 3. Generate the results. 4. Format the results inside a document. 5. Set the appropriate HTTP response parameters. 6. Send the document back to the client. JSP Java Server Pages (JSP) technology enables you to mix regular, static HTML with dynamically generated content from servlets. Many Web pages that are built by CGI programs are primarily static, with the parts that change limited to a few small locations. JavaServer Pages (JSP) technology lets you put snippets of servlet code directly into a textbased document. A JSP page is a text-based document that contains two types of text: static data (which can be expressed in any text-based format such as HTML, WML, and XML) and JSP elements, which determine how the page constructs dynamic content.

FEASIBILITY STUDY A feasibility study is conducted to select the best system that meets performance requirement. This entails an identification description, an evaluation of candidate system and the selection of best system for the job. The system required performance is defined by a statement of constraints, the identification of specific system objective and a description of outputs. The key consideration in feasibility analysis are : Economic feasibility: The proposed system is economically feasible because the cost involved in purchasing the hardware and the software are within approachable. The personal cost like salaries of employees hired are also nominal, because working in this system need not required a highly qualified professional. The operating-environment costs are marginal. The less time involved also helped in its economical feasibility. The benefits of this project include four types:  Cost – saving benefits  Improve-service-level benefits  Improve-information-level benefits  Time-saving-benefits Technical Feasibility: Technical feasibility is the study of available technology to implement the system and the suggested alternatives. Technical feasibility determines whether the work for the project can be done with the existing equipment, software technology and available personnel. Technical feasibility is concerned with specifying equipment and software that will satisfy the user requirement. Behavioral Feasibility: People are inherently resistant to change and computers have been known to facilitate changes. An estimate should be made of how strong a reaction the staffs are likely to have towards the development of an online computerized system because now this may lead to expulsion of some of the staffs from their jobs. So a system has to be chosen which will provide them much more facilities and less mental disturbance to check weather correct entry is entered and that too at its right place. The System will provide them automatic reporting and checks on entries while storing as well as entering.

ANALYSIS/TESTING In this project the Waterfall model is used which is a systematic, sequential approach to the software development that begins in the software level and process through analysis, design, development and coding, testing and maintenance. It suggests a linear progression of framework activities that is often inconsistent with modern realities in the software world. It have applicability in situations where requirements are well defined and stable. The stages involved in waterfall model are as follows: 1. Requirement Analysis and Specification. 2. Design. 3. Implementation. 4. Unit Testing. 5. Integration and System Testing. 6. Operation and Maintenance. The waterfall model emphasizes on requirement analysis and design. Before writing a single line of code it ensures minimal wastage of time and effort and reduces the risk of schedule slippage, or of customer expectations not being met. By doing so it improves quality; it’s much easier to catch and correct possible flaws at the design stage than at the testing stage, after all the components have been integrated and tracking down specific errors is more complex. The advantages of waterfall model are: 1. Reduces the problem of code and fix method. 2. It allows for communication between customer and developer and specifies what will be delivered, when and at what cost. 3. Minimum wastage of time. The disadvantages of waterfall model are: 1. This model is rigid because it assumes that a phase is fully complete before another one commences. 2. Requirements must be known at the beginning before the project commences. 3. Risk assessment factor is not present. 4. Redesigning is difficult. Software Testing is the process of testing the software product. It is an important activity of software development process. Effective testing will produce quality software products. The testing requires the developers to find errors from the software. The principles are testing are:  All tests should be traceable to customer requirements.  Tests should be planned long before testing begins.  Testing should begin in the small and progress toward testing in the large.  Exhaustive testing is not possible.  To be most effective, an independent third party should conduct testing. Unit Testing is the testing which is done at the first stage. In unit testing only one component of the system is tested, i.e., it includes the testing of only one module. After unit testing comes Integration Testing. In this level, many unit-tested modules are combined into subsystems, which are then tested. The goal of this testing level is to see if the modules can be integrated properly. This testing activity can be considered as testing the design. 11 | P a g e

In our project we carry out alpha testing and white-box testing and black-box testing. Alpha testing is performed by the development team within the developing organization. White-box testing is involved directly with the structure of the code within a module or code segment. In this a directed graph is drawn and use it to plan tests which adequately covers all the code in a given module. It tends to involve coverage. Its types are:  Segment Coverage.  Branch Coverage or Node Coverage.  Compound Condition Testing.  Basis Path Testing.  Data Flow Testing.  Path Testing.  Loop Testing. Black-box testing consists of assuming that the logic structure of the code is unknown-that is a ‘black box’. This is the point at which the function of a module is tested. It mainly involves:  Error Guessing.  Equivalence Class Partitioning.  Boundary Value Analysis.  Cause-and-Effect Graphing.  Domain Testing.  Module Interface Testing.  Command Line Testing.

MARKET POTENTIAL There are several reason why marketing online has become extremely important to the competitive real estate agent.  71% of homebuyers use the Internet for research and to search for listings.  Internet homebuyers make better clients  It saves time and is more cost effective than most traditional forms of marketing Millions of Homebuyers Hit the Internet for Information The Internet is the first place more and more homebuyers are beginning their search for a home. According to a study done by the National Association of Realtors, 71% of homebuyers take their search online. These numbers will only increase with the Internet reaching more and more households. Nearly 70,000 new people are getting Internet access every day. Studies also show that the average homebuyer is also getting younger, and increasingly grew up with the Internet. Internet Homebuyers Make Better Clients According to a study commissioned by the California Association of Realtors, Internet homebuyers were reported to be wealthier and purchasing more expensive homes. Internet homebuyers bought a median priced home of $452,000 while traditional buyers purchased a median priced home of $310,000. In the same study, homebuyers also reported that the Internet shortened their home search. The entire home purchasing process took half as long for homebuyers who used the Internet as those who did not. More importantly, Internet buyers spent half as much time with their real estate agents, visiting only half as many homes as traditional buyers before making their purchase. They were able to view listings online and narrow down their search to the few homes they were strongly interested in. Homebuyers using the Internet were also more knowledgeable about the purchasing process, and expressed greater satisfaction with their real estate agents. More expensive purchases, shorter search cycles, and happy clients who are better informed about the home-buying process -- could it get any better? In fact it does! Homebuyers who search the Internet are actually more likely than traditional buyers to use a real estate agent to find their home and complete the purchase. 77% of Internet homebuyers use a real estate agent, compared to only 70% of those who do not take advantage of the Internet. Online Marketing Saves Time and is Cost Effective In addition to the huge audience of excellent prospective clients, the Internet offers both convenience and cost effectiveness that traditional media cannot. Web sites are more engaging and informative than even the best brochures. You do not need to have a four or five-figure marketing budget to create a professional online presence. Other advantages are:  State-of-the-art filtration tools: Leading real estate sites offer people the latest technologies and filtration criteria that help them find properties in the easiest, most rapid and efficient way.  Sophisticated management tools: The entire process is managed from one location which allows posting requirements, listing properties to allotments , prioritize and contact callers individually or collectively and track all activities from the confines of a private and highly functional Workspace. This allows for an enhanced user experience for all the users.  Allows for confidentiality: Individual, agent and builder can elect to maintain their confidentiality.  Allows for proactivity: The buyer/seller is in full control of the allotment process.  Allows for database build-up. 99 | P a g e
