Question

How are activity diagrams used in describing the context of use of a system:

A.) Activity diagrams may be used to describe actors and functions of the system.

B.) Activity diagrams may be used to describe the business processes in which the system is used and the other systems which are also used in the processes.

C.) Activity diagrams can be used to describe various objects and their interaction.

Answer 1

Activity diagrams are used to model business processes and workflows, describing the system's context and interactions with other systems and actors.

Step-by-step explanation:

Activity diagrams are employed to model the flow of control or data among various activities and actors in a system, and are particularly useful in representing business processes and workflows. They offer a way to describe the context in which a system operates by showcasing how a user interacts with a system and how different components and actors work together within a business process. Answer B effectively describes the use of activity diagrams by stating that they may be used to depict the business processes in which the system functions and the interaction with other systems within these processes. This approach to diagramming helps in understanding the system's role and its relationships within the broader operational context of an organization.
