In the context of use case modeling, a primary actor is the entity that initiates an interaction with the system to achieve a goal. This actor is crucial in defining the system's requirements and ensuring that the system's functionalities align with user needs.

Primary Actor

Use case modeling is a technique used in systems analysis to capture the functional requirements of a system by describing how external actors interact with it. It provides a high-level view of the system's functionality and helps ensure that all user interactions are considered during the design process.

Use Case Modeling

An entity is a distinct, identifiable unit in a given context, often used in fields such as database management, law, and business to represent objects, people, or concepts with specific attributes or characteristics. Understanding entities is crucial for organizing, categorizing, and managing information effectively across various domains.
