Suppose you are working as Domain Analyst in a renowned software house ABC. You have been given a task to model requirements for a software project i.e POS System.
A POS (Point-Of-Sale) system is a computer system typically used to manage sales in retail stores. It includes hardware components such as a computer, a bar code scanner, a printer and also software to manage the operations of the store.
The basic function of a POS system is to handle sales. When a customer arrives at a POS counter with some products to purchase, the cashier will start a new sale transaction. When the barcode of a product is read by the POS system, it will retrieve the name and price of this product from the backend inventory system and deduce the stock amount of this product. When the sale transaction is over, the customer can pay in cash or via Debit Card. After the payment is successful, a receipt will be printed.
Work flow of the system is as follows:
Use Case Diagram for POS System
In Assignment No.2, you are required to draw a Class Diagram (1-page) of the above scenario by
identifying classes, its attributes and related functions. You have to show the relationship among different classes like Composition, Aggregation, Inheritance and Association.
Your solution must conform to the concepts of Object Oriented Design paradigm like Abstraction, Coupling, Cohesion, Encapsulation etc.
Assignment No.1 and its Solution will provide you the basis to solve this assignment#2. Lecture No.15 to onwards will be helpful for you to develop a strategy about how to find out classes, attributes, functions, relationship etc. for Object Model.
Your assignment must be uploaded/submitted on or before 30-06- 2016.
Wish you very best of Luck!
