Overview

This tutorial will provide a basic understanding of the elements in a use case modeling. There are many benefits of use case model. We can use Use case modeling tools to develop use cases for the project.

Use Case

Use case describes the interaction steps of the use case actor to use the system and achieve business goal.

An Actor is an external entity that interacts with the system being developed to achieve business goal. Actors are often humans, but this is not a requirement. Actors can be other software programs, systems, hardware device, an API, a batch job scheduler etc.

It’s important to note that an actor represents a role, not a specific person or entity in the real world. A specific person could play the role of more than one Actor in a system.
