Course Title: Object Oriented Analysis and Design
Question :
There is a utility company which provides waste management services to citizens. It has a CRM system, billing system, messaging system and mapping (GIS) system. When a customer is created in the CRM system, the billing, messaging, and GIS systems need a copy of customer data to perform follow-up tasks and automation. For instance—the billing system will create a billing account for the customer, the messaging system will send a welcome message with customer account details on preferred communication channel and the GIS system will update the customer’s address in the database for mapping purposes. After completion of one billing cycle the billing dept. sends a copy of the bill in a pdf format on the customer email address and the bill amount is directly debited from the customer’s bank account.

Object-oriented design needs to be used whenever it makes sense to do so. Structured design is a choice that can be used when the situation calls for it. what might be making this happen, etc.
Practice Programming Planning Problems using Object Oriented Design– Outline the classes and relationships and describe the programming process for an "automatic meeting scheduler using inputs from a calendar database." Use a simplified version of Unified Modeling Language class diagram. You are not writing the code for this, just the design and the algorithm.
