System Overview

Description of the application associated use case scenarios

Description:This is an e-commerce application that will enable customers to shop online and also provide an administrative interface which will allow members of staff to keep track of customers’ orders. The application must have following minimum functionalities.

This e-shopping software is designed in client server model. The sever side of this software uses JSP, Servlets and java bean class [ J2EE frame work]; the database used is mySql. The clients /staff can access through web browser which is java enabled. JSP is used for the user interface creation for the dynamic pages, but this will be converted to plain html and sent to the client machine.

Model-view-Controller pattern is used for the design. This gives modularity and low coupling to the design. The changes in one layer will not affect the other layers in the system. I.e., Changes in user will affect only userBean of model layer. All the servlets belongs to Controller layer of this design. This will perform request parsing first; in the second step it will create corresponding model class /classes to perform the business logic; and at the last it will forward the control to view class with the result.

JSP [java Server Page] files forms the view layer of this design. These files will generate dynamic html with the result values forwarded by the controller Servlets. View layer is the presentation Layer in the design. This will have the user interface to interact with the End Users of the system. JSP tags will be embedded in html pages and while execution these tags will be converted to servlets.

Model layer does the business logic of this software. A number of Java bean classes build this layer. In this design model layer is again split into tree sub layers for more modularity. The first layer consist of entity classes , the second layer consists of DB access classes and the third layer id the Database Connector class. All the database connection related information is isolated to the third Layer, this kind of a design makes it easy to change from one software vendor to other. And only one class need to be modified for this. Access lasses will have sql queries for the data manipulation from the database. This layer will help in realizing the entity classes. Entity calluses will perform the core business logic through its methods with the help of Data Access Layer.
