A use case is a description of how a user uses a system to accomplish a particular goal. It is represented by a sequence of actions that the user takes in order to achieve the goal. In software engineering, a use case is a tool used to capture the functionality of a system.

A use case in software engineering is a scenario that describes how a user might interact with a software application. A use case scenario typically includes a description of how a user would interact with the software to accomplish a specific goal. For example, a use case scenario for an online shopping application might describe how a user would search for and select a product to purchase, add the product to their shopping cart, and then checkout and pay for the product.

Use cases are a way of representing user requirements in a software system, and can be used during the software development process to help ensure that the system meets the needs of its users. Use cases can also be used to help create test cases to test the functionality of the software.

A use case example in software engineering is when a user wants to log in to a system. The system uses a case to verify the user's identity and then allows the user to log in.
