What is a use case in software engineering?
a) A description of how users interact with the system to achieve a goal
b) A description of the database schema
c) A set of rules for testing software
d) A prototype of the user interface
Answer:
a) A description of how users interact with the system to achieve a goal
Explanation:
A use case is a description of how users (actors) interact with a system to achieve a specific goal. It outlines the steps or actions that users perform and how the system responds to those actions.
Use cases are a key component of requirement analysis and help developers understand what the software needs to do from the user’s perspective. They focus on capturing functional requirements and scenarios of user-system interaction.
Use case diagrams, part of the Unified Modeling Language (UML), are often used to visually represent the interactions between users and the system.
