Sample application:

This following is a sample e-commerce application. Let’s assume that you have been hired by Nile Company (Amazon’s competitor) to keep track of their inventory. Nile sales two types of products: games and toys.

Requirements

Your goal is to create an online store for the Nile Company. There will be three types of users:

• customers

• staff

• manager

Customers In order to purchase from Nile, customers must first register. Once they are registered, they query and purchase books or toys. These items are first placed in a shopping basket, and then ordered. Customers can see the status of orders (i.e., pending or shipped).

Staff can check inventory, re-stock the online store with more components, view all customer orders, and ship orders to customers. A staff member has an on-line ID and a pass word that he/she can use to login into the company’s website to perform the previous listed tasks

Manager can do all tasks a staff member can do. In addition, manager can (1) view statistics about sale information (in the previous week, month, or year), and (2) decide sales promotions. Manager needs to login into the company’s website to perform the tasks.

The following functionality might be provided:

Customer Forms

Register Allows a new customer to register with NILE.

Shopping Allows a registered customer to list books or toys. The purchased items may be stored in a shopping basket.

Purchase Allows a registered customer to view their shopping basket and click "Purchase". This creates an order for the items that can then be viewed (and filled) by the NILE staff. NILE staff cannot see shopping baskets.

Orders Allows a registered customer to view the orders they have places and see the status (either Pending or Shipped).

Staff Forms

Login Screen Staff must login in order to perform these functions. A single login for all staff is fine.

View Inventory See a list of all items and their quantity.

Update Inventory Same as above, but with editable text boxes to change the quantity of any component.

Ship Pending Orders View the list of pending orders (components, price, customer info).

The staff member can click a "Ship It" button and, if all the components are available, the status of the order changes from "Pending" to "Shipped" and the quantities in the inventory are decreased. If the components are not available, some error page listing the missing components is generated and the order remains "Pending".

Manager Forms

Login Screen may use the staff login form

View Inventory, Update Inventory, Ship Pending Orders: the same as those of staff

Sales Statistics View the list of all items and sales history in the previous (week, month, or year)

Sales Promotion View the list of all items and decide the promotion rate.
