Overview of class modeling

UML Modeling Techniques > Class modeling > Overview of class modeling

Class Modeling focuses on static system structure in terms of classes (Class, Data Type, Interface and Signal items), Associations and on characteristics of Classes (Operations and Attributes).

Modeler provides Class Diagrams and Composite Structure Diagrams to support the definition of the Class Model:

• The Class Diagram is the primary diagram for defining Classes and their Attributes, Operations and relationships. The Class Diagram notation is based on the Unified Modeling Language (UML).

• The Composite Structure Diagram defines the structure of Classes, in particular, showing how Class parts and ports connect with each other. The Composite Structure Diagram notation is based on the UML 2.0 notation, with the addition of SysML IO Flows.

The following table summarizes in which parts of Modeler you can create the Class Model items.
