USE CASE Meaning and
Definition
-
A use case is a term commonly used in software engineering and systems development to describe a specific interaction between an actor (user) and a system or software application. It is a way to capture and document the functional requirements of a system by illustrating how it is used to achieve certain goals or perform specific tasks.
In a broader sense, a use case is a representation of a scenario or situation that demonstrates the way a system or application is intended to be utilized by its users. It outlines the sequence of steps or activities that a user would go through, providing a detailed analysis of the expected interactions, inputs, and outputs involved in the process.
A typical use case consists of various components, such as the primary actor (user), secondary actors (other systems or external entities), preconditions (requirements that should be met before the use case starts), main flow (the primary steps leading to the desired outcome), alternative flows (alternative paths or exceptions), and postconditions (expected outcomes or results).
Use cases are created to ensure that functional requirements are well-documented, understood, and communicated among software developers, stakeholders, and clients. They serve as a valuable tool in software development, as they help to clarify the system's behavior, identify potential problems or gaps, and serve as a basis for system testing and validation.

Etymology of USE CASE
The term "use case" has its origins in the field of software engineering and system analysis, specifically within the domain of Requirements Engineering. It was popularized by Ivar Jacobson, a Swedish computer scientist and one of the founders of the Unified Modeling Language (UML).
The word "use" in "use case" refers to the primary objective or purpose for which a software system or a specific feature is designed to be utilized. The term "case" indicates a specific scenario or situation in which the system or feature is applied.
The concept of use cases emerged as a way to describe the functional requirements of a system from the end-users' perspective. Use cases are used to capture different interactions between users and the system, describing the desired behaviors and outcomes. They serve as a means to understand and communicate the system's objectives and functional capabilities.
