UML
The UML (Unified Modeling Language) is an international industry standard graphical notation for describing software analysis and designs.
Fundamental UML models
There are five fundamental UML models:
- Use case model
- Class model,
- Sequence model
- State model
- Activity diagrams
Use case model
The use case model consists of:
- A use case diagram,
- A set of use case descriptions,
- A set of actor descriptions, and
- A set of scenarios.
A use case diagram
The use case diagram models the problem domain graphically using four concepts:
- The use case,
- The actor,
- The relationship link, and
- The boundary.
UML symbols used to model these concepts:
