Use Case Diagram

What is Use Case Diagram

A use case diagram is a type of UML (Unified Modeling Language) diagram that shows the interactions between actors and systems in a software development project. Actors are typically people or external systems that interact with the system, while the system itself is represented by a rectangle. Use cases, which represent specific actions or functions that the system can perform, are represented by ovals and are connected to the actors and system with lines.

The purpose of a use case diagram is to model the functional requirements of a system and to show the relationships between the actors and the system. It is a useful tool for visualizing and documenting the interactions between actors and the system, as well as for identifying the specific requirements and capabilities of the system.

Here is an example of a simple use case diagram:

[Diagram of a simple use case diagram showing an actor (customer) interacting with a system (online store) through various use cases (browse products, place order, track order, etc.)]

In this example, the actor (customer) is able to interact with the system (online store) through various use cases, such as browsing products, placing an order, and tracking an order. The use case diagram helps to visualize and document these interactions and the specific requirements of the system.
