Rules of UML

Well formed models semantically self-consistent and in harmony with all its related models.

Semantic rules for:

Names — what you can call things.

Scope — context that gives meaning to a name.

Visibility — how names can be seen and used.

Integrity — how things properly and consistently relate to one another.

Execution — what it means to run or simulate a dynamic model.

Avoid models that are

    Elided — certain elements are hidden for simplicity.

     Incomplete — certain elements may be missing.

     Inconsistent — no guarantee of integrity.
