4 1.4 Project Scope This Online Book Store provides an easy way to browse, search, and shop for books online. This Online Book Store put each book in a category so the user can reach specified book by surfing a specified category or by using the search function (by name or ISBN) which is implemented in this software. The software allows the users to browse all the information about a particular book like the title, author name, publishing year, ISBN if it is global book, number of pages, best store and compare prices. The software allows the users one or more books by add books to the shopping cart. When the customer finished and wants to order the selected books, he will be directed to one of the biggest stores that sells books such as: Amazon or Barns & Noble stores to continue purchasing and shipping information. 2. Overall Description 2.1 Product Perspective This application is going to be developed using Adobe Flex SDK to create user interface and GUI components like graphics, buttons, containers, labels, text and anything that the user will deal with or watch. Also we are going to use Action Script version 3 along with Flex SDK to create the actions that is fired by the user like searching for a certain book, adding books to shopping cart, browsing categories. Flex SDK will generate an executable file (.swf file) which runs using Adobe Flash player that is embedded in the web browser. 2

5 This exe file or SWF will be upload with some other required data to server. On the server side we are going to use PHP programming language which extract and returns dynamic XML data from a database table (created by SQL) that contains information associated with the books like title, author, ISBN, description etc, this data is requested by swf file. Flex SDK offers some services to communicate with the server side such as : HTTPService which allows us to utilize the data (XML file) returned by PHP server to fulfill the requested data by the user or the swf file in general. 2.2 Product Features This a summarized features for the software: Books are grouped in categories. This Online Book Store has search function. High performance due to scripting and RIA technology. Providing most important information of the books listed in the website. Well designed, ease of use and friendly interface for promotion purposes. The user can shop for on book or many books by implementing the add to cart function. 2.3 User Classes and Characteristics There is various user classes that can get benefit from this application. Such as : Learning Centers or Universities : learning centers may publish their books for selling online to make easy for their customers to choose book then buy it from the center offline. The university can publish the books that needed for each department making it easier for the students to find their needs. 3

6 Anybody wants to buy a given books in particular to university students or instructors. Companies that s interested in it or anyone wants to make some money from selling books. Bookshops and libraries 2.4 Operating Environment As long as this application runs on the browser it does not need any installation or to be combatable with an any operating systems like Windows, Linux, Macintosh or any other OS. The only thing required is to install the latest version of Adobe Flash Player plug-in for the browser that is used by the user. This application will run on any web browser that support the flash player plug-in such as: internet explorer, Mozilla Firefox, Opera, Netscape. etc. 2.5 Design and Implementation Constraints The main problem that faces the developer that they have to learn some programming languages like Action script 3 and PHP also they need some acknowledgment in database tables creation using SQL. The developer team also have to learn to use Adobe Flex builder which is the tool they need to design user interface and GUI components. This website and the application must be uploaded to server in order to get benefit from it, but as this software is for purpose of learning only developer team will use local server which will be created using Apache server or PHPMyAdmin or WampServer programs. For the issues concerned with maintaining and website feeding it must be discussed with the customer s organization in order to determine if the developers will be 4

7 responsible for website maintaining and site feeding for some months until the website become bigger then customer s organization will be responsible for this issues or there is another scenario. 2.6 User Documentation This application will be delivered with this documentations: Online help: menu in the website that holds the application tells the customer how to use the software to get the maximum benefit from it. Report for the project manger and software customer explaining all the issues that concerned with this software. 2.7 Assumptions and Dependencies About the ordering shipping process : This software just allows the customer to find the books they need and allows them to deal with all the function about searching, browsing for books information, choose multiple books to be. But the steps concerned with purchasing and shipping will be a reasonability of a third party websites The exe file that will be generated from Flex SDK (SWF file) is depending on the plug-in of Adobe Flash Player to be installed in the customer browser, if not the user may find some difficulties in running the software. During developing process the developers may be use ready-made classes from internet from other similar projects like: classes implements GUI components. 5

8 3. System Features 3.1 Books are grouped in categories The books that have same topic are grouped together in a category in order to make it easy for the user to surf the books that have the idea. Also there is category for the best seller books and another for the newly added books to the store. 3.2 This Online Book Store has search function This store may contains thousand of books with thousand of topics and titles, so the search is a must here to help user to find their needs. The search function will be implemented to search by name of book or by ISBN if the book is global one. This function will search through the database table that will be on the server side this may make the application slower but there is no other solution to implement this. 3.3 High performance due to scripting and RIA technology. There is no need to contact the server side in each time the user make an action on the site because of using scripting language which is Action Script 3.This technology make the process of surfing and browsing of the books more faster than we use HTML or PHP forms only as in this case the page must be refreshed each time. 3.4 Providing most important information of the books listed in the website. This information includes : ISBN Book title Book price Book author 6

9 Description Date of publishing Number of pages 3.5 Ease of use and friendly user interface The store does not contains any difficult actions or not understandable actions, besides that this store must have excellent interface and GUI to grab more users and make the more comfortable while they are surfing, searching and reading. 3.6 Add to cart function This function allow the user to permanently bookmarks the books he needs to buy rather than buying one by one, that save the time of the user and makes the books shipped all together. 4. External Interface Requirements 4.1 User Interfaces The software interface will be divided into three vertical columns. The homepage of the application which lists new books and bestselling books in the middle section, and also provides category navigation menus on the left-hand side. You can also see a SHOPPING CART link on the right-hand side, which will list the current books selected by the user as shown here: 7

10 Th e following is the product listing screen. It lists all the books available in the selected category when a user selects any specific category from the navigation menu. The following screen displays the selected book's details in a pop-up window when a user clicks on the Details button on the book widget. 8

11 Users can also add or remove books from the shopping cart. The shopping cart updates the shopping details dynamically and provides an option to remove a specific book or change its quantity. 4.2 Communications Interfaces This software will communicate with the database that created to hold books information SWF file can contact with server side through HTTP protocol by means of a function that is called HTTPService. This function allows the application to use the data retrieved by server (XML file) to fulfill the request fired by the user. 9

12 5. Other Nonfunctional Requirements 5.1 Performance Requirements This software will run on the web browser using flash player (.swf file) which is implemented in the most web browsers so the performance of this application is depending on the speed of the internet connection of the customer is it slow the user have to spend longer time waiting the component of the application to loaded. But if we compare the technology we use to develop this store which is action script 3 and flash (at its heart is MXML, a markup language based on Extensible Markup Language (XML)) with other technology like pure HTML or PHP we will find that we choose the best technology because the user do the actions like selecting, filtering and browsing the book information in the browser without the need to contact with the server side in each action done by the user unlike other programming languages like PHP. 5.2 Safety Requirements The safety issues for this application will be concerned of the status of the shipped books, package damaging time to deliver and customer information. As the ordering process will not be in the same website that contains the software so it will not deal with any privacy information about the customer also it will not deal with any shipping process as the customer will be directed to one of the most secure, safe, reliable stores on the internet (Amazon or Barns & Noble stores) to complete the ordering and the shipping process and will not be responsible to any damage or shortage or late could be happened in order shipping. 10

13 5.3 Security Requirements The Security issues for this application will be concerned of the customer information like the name, contact information like address or phone number, shipping address, credit card number etc. As the ordering process will not be in the same website that contains the software so it will not collect any privacy information about the customer as the customer will be directed to one of the most secure, safe, reliable stores on the internet (Amazon or Barns & Noble stores) to complete the ordering and the shipping process. You may be want to check the privacy policy and the terms of use for the mentioned websites.
