SOFTWARE ENGINEERING: ANALYSIS AND DESIGN
Introduction
Bob and Alice are a small business owner, and they would like to improve their
business transaction. They want to offer various credit card payment options to allow the
customers to purchase when they have not enough cash in their hand. And they also like to
add a Bitcoin payment in the near future. In this report, we will discuss the requirements
designs and analysis to virtually representing the system. Next, the implementation of the
payment system that allows to enter total purchase amount and to select a payment method
either a cash payment or card payment will be discussed. For payment using cash, there is no
addition of surcharges. For payment using the card, the program calculates the total amount,
including surcharges. Finally, the object oriented programming concept that is used to
achieve the system are discussed.

Use Case Diagram for Payment Processing System
 Use Cases summarizing the requirements of the program
Objects involve in Used Case Diagram:
• Use Case: this represent an action or a function inside the system.
• Actor: this represents an entity in the system who perform an action.
• Package: this represents an optional element in the complex diagram. To group multiple uses cases
packages can be used.
• System: this describes the scope of a use case system and represented by a rectangle. This is
optional but it can be used to visualizing a large system.
 A Class Diagram of the intended system
