In UML, there are two main types of modeling: structural modeling and behavioral modeling. Structural modeling focuses on the static structure of the system, its parts, and how they are related to each other. They do not show details about the dynamic behavior of a system. Some of the structure diagrams in UML include:
- Class diagrams
- Component diagrams
- Package diagrams
- Deployment diagrams
Behavioral modeling shows the dynamic behavior of the components in a system. Unlike the static nature of structure diagrams, behavior diagrams describe changes to the system over time. Some of the behavior diagrams in UML include:
- Use case diagrams
- Sequence diagrams
- Activity diagrams
