About Diagrams

Diagrams are the way UML Modeling displays static structures in your system. When you create a diagram, it is displayed in the Projects window under the current project node. You can create as many diagrams in a project as you need. Each UML Modeling diagram consists of two distinctly different types of data, each saved as a different file with different file extensions.

UML Modeling lets you work with eight types of diagrams. The table below describes each type of diagram:

Type Description
Activity Diagram A visual representation of any system's activities and flows of data or decisions between activities.
Class Diagram A visual representation of any system's objects and the relationships between them.
Sequence Diagram A visual representation of the interaction between collaborating groups of objects in a system.
State Diagram A visual representation of the state machines. It shows the behaviors that make up the sequence of states that an object goes through during its lifetime in response to events, together with its responses to those events.
Use Case Diagram A visual representation that shows a set of use cases and actors and their relationships. Use case diagrams address the static use case view of a system.
