Detailed explanation-1: -Use case diagram provides a simple, straightforward way of communicating to the users of what the system will do, and also disseminate different kinds of users that will interact with each functionality system.
Detailed explanation-2: -Use-case diagrams illustrate and define the context and requirements of either an entire system or the important parts of the system. You can model a complex system with a single use-case diagram, or create many use-case diagrams to model the components of the system.
Detailed explanation-3: -The use-case model is used like the main specification of the system functional requirements as the basis for design and analysis, as the basis for user documentation, as the basis of defining test cases, and as an input to iteration planning.
Detailed explanation-4: -A use case diagram is used to represent the dynamic behaviour of a system. It encapsulates the system’s functionality by incorporating use cases, actors, and their relationships. The collaboration diagram is used to show the relationship between the objects in a system.
