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. Draw an appropriate Activity diagram for the same system. (Note): Forks and joins have the same notation: either a horizontal or vertical bar (the orientation is dependent on whether the control flow is running left to right or top to bottom). They indicate the start and end of concurrent threads of control. In the scenario given above; try to find a situation where the use of Forks and Joins can be demonstrated
