Detailed explanation-1: -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.
Detailed explanation-2: -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-3: -Use cases are text stories, widely used to discover and record requirements. A use case encapsulates a set of actions that are executed in a well defined order. Use cases influence many other artifacts, e.g. analysis, design, implementation and test artifacts.
