MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -Functional requirements are a set of requirements, mostly in text form that defines the system functionality being developed. Use case diagram is requirements elicitation of a software system. Both can be used and there are clear advantages in doing so.

Detailed explanation-2: -Use Case Diagram A cornerstone part of the system is the functional requirements that the system fulfills. Use Case diagrams are used to analyze the system’s high-level requirements. These requirements are expressed through different use cases.

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: -Use-case diagrams describe the high-level functions and scope of a system. These diagrams also identify the interactions between the system and its actors. The use cases and actors in use-case diagrams describe what the system does and how the actors use it, but not how the system operates internally.
