Project Description

AAA is an application which allows store employees to purchase "hot" items at an additional discount. This application has two main interfaces: Store Operations access the application from core TOMCAT to create new AAA items. During each sales transaction, Store21 performs verification to determine eligibility for AAA sales. The AAA UI is implemented by using technology Spring MVC/Webflow. To implement this we have defined view-state for a JSP page. In the view-state is an XML file where we defined the state of a page by using Webflow. For example if the next button is pressed this will call Action class and will send some information to next page when it gets displayed. In the view-state file we need to define the flow of each page and there actions. The user interface is divided into three modules:

Country Control: In this one has to create discounts on a country level, can edit discounts. Once the discounts are created or edited, it will allow approving those discounts

Create AAA: In this module one can create an AAA for an employee or for a store based on job code and job group code. Once a AAA is created on a store level for a country. If any employee of AnF goes to a store to buy an item, during that time when a cashier swaps the card of that employee it checks in the background whether that employee is eligible for an AAA or not and it will tell how much discount he can avail and based on that the bill will be generated for that employee

Store Control: In this module one can create a new store control, edit store control and approve store control. This module will tell that for which stores and for which brand an employee who is working in a store or in home office can avail discounts
