1. Introduction

1.1 Purpose

The following is an SRS (Software Requirements Specifications) that will define the requirements and specifications of the Home Locator Project.

1.2 Project Scope

This system will make the searching for homes to rent or buy more easy to people , it will be available as a web application ,so all people can reach it with the minimum software and hardware requirements , they just need the Adobe Flash player 9 or above .

The system will provide an easy way for searching by a lot of categories available.

2. Overall Description

2.1 Product Perspective

The idea of the system is a new idea , with the respect of the definition of WEB2.0 term , we can call the system a “Web2.0 Application” , visitors can add homes they want to be rented or buy . The visitors can locate a specific home and call the owner immediately to meet him . the next figure illustrate this process .

Figure .1 – The Main Function of the system.

Ft. , Price , bedrooms , bathrooms ..... etc ) , also it will provide the exact location of the house by mark it on the map , and it will give a lot of information about the house to the visitor .

2.3 User Classes and Characteristics

There is two classes of users in the system . The visitor : he can search and locate houses , and he also can add houses to be rented or

The Administrator : he can add houses , approve and verify houses that added by visitors , managing the database . Figure .2 – The Characteristics and scopes of users .

2.4 Operating Environment

We need to install the System to a web server has the following programs : Apache Server PHP 5+ Compiler Mysql 5+ DBMS.

The visitor need these applications to access the system : A modern web browser like IE7+,Firefox 3+,Opera9+,Chrome and Safari. Adobe Flash Player 9+.

2.5 Design and Implementation Constraints

The main constrain that will the developers face that they will need to design the application for a future extendable feature because the system will support Homes in USA only , The whole world is not mapped yet , so the developers must design the application to contain the whole cities in the world if they come available .

2.6 User Documentation

There will be a section from the website where the administrator can add tutorials for the visitors .

Figure .6– All Sections together .

4.2 Software Interfaces

The application will built on Adobe Flex Environment with ActionScript 3 Language , and I will use PHP Language as a server side language with version 5.2 . as a DBMS I will use PhpMyAdmin , as Database I will use Mysql version 5.0 , as Map library I will use Yahoo Maps API .

4.3 Communications Interfaces

For the communication between The application and the database I will use HTTP Simple Requests with JSON technique to get the response data .

5. Other Nonfunctional Requirements

5.1 Performance Requirements

The software must be fast in getting the houses and its information .

5.2 Security Requirements

The software must be secure as possible as you can , especially in the adding houses area , this is can be achieved by strip any malicious codes that user may put insert it in the adding houses form .

5.3 Software Quality Attributes

5.3.1 Reliability The system must has height reliability because it use height security on network and I use Mysql that offer to us to implement the security very well.

5.3.2 Availability The system will be available to everyone, and the system will be Web-based / on-line

access to the system, 24/7 5.3.3 Maintainability

To keep the system run very well I must do testing to it every each period If there is error accrues in the system I will do maintenance to the subsystem that error accurse in it.

5.3.4 Transferability/Portability The system will run on any OS and do not need to specific platform to run. 5.3.5 Learn ability

The system will be so simple and not complex and it is so familiar that help the user to learn using it in short time.
