Model Validation

model_validation

You use Model Validation to check UML models against known UML rules (which you identify in configuring validation) as well as any constraints defined within the model, using the Object Constraint Language (OCL). You can run Model Validation against a single UML element, a diagram or an entire package.

Validating

Validating a UML:

•Element validates the element and its children, features (attributes and operations) and relationships (connectors)
•Diagram validates the diagram itself (for correctness) as well as any elements and connectors within the diagram
•Package validates the package and all sub-packages, elements, connectors and diagrams within it

 

 

Example - Model Violation

The following UML diagram contains several basic violations:

 

ModelValidationExample

 

If you run Model Validation on this diagram, Enterprise Architect displays the following violations in the Output window:

•It contains a UML ExpansionRegion (ExpansionRegion1) that is missing its child input ExpansionNode
•It contains an invalid self-generalization on Class2 (UML elements cannot be self-generalized)
•It contains an OCL violation for the anonymous Association (between Class2 and Object1)
•It contains a UML ExceptionHandler (ExceptionHandler1) that is missing its child input ObjectNode
