StarUML Programming:

Tosco's wholesale requires a new point of sale and stock control system for its many stores throughout the Tri-state area (New York, New Jersey, Connecticut) to replace its ageing mini based systems.

A sales assistant will be able to process an order by entering product numbers and required quantities into the system. The system will display a description, price and available stock. In-stock products will normally be collected immediately by the customer from the store but may be selected for delivery to the customer's home address for which there will be a charge. If stock is not available the sales assistant will be able to create a backorder for the product from a regional warehouse. The products will then either be delivered direct from the regional warehouse to the customer's home address, or to the store for collection by the customer. The system will allow products to be paid for by cash or credit card. Credit card transactions will be validated via an online card transaction system. The system will produce a receipt. Order details for in-stock products will be printed in the warehouse including the bin reference, quantity, product number and description. These will be collected by the sales assistant and given to the customer. The sales assistant will be able to make refunds, provided a valid receipt is produced. The sales assistant will also be able to check stock and pricing without creating an order and process orders that have been created for delivery.

The store manager will be able at any time to print a summary report of sales in the store for a given period, including assignment of sales to sales assistants in order to calculate weekly sales bonuses.

The stock manager will be able to monitor stock levels and weekly run-rates in order to set minimum stock levels and requisition products which fall below the minimum stock levels or for which demand is anticipated. When the stock arrives it will be booked in by the warehouse person. Stock that has been backordered for collection from the store is held in a separate area and the store manager advised of its arrival.

The catalogue of available products will be maintained remotely by marketing from head office. Marketing will also be able to access sales information from each store system. (Any similarity between this fictional example and any existing store is entirely coincidental)

Your Task:

Using the Tosco's Problem Statement given above, use StarUML to create a use case diagram of the requirements for the store system. I have not provided you with absolutely all the information you need to do this so you will need to use your discretion. In the real world you would ask the users or business representatives.
