摘要：

This paper discusses integrity constraint evolution, from two perspectives: From the perspective of changing the constraint, and from the perspective of consequently changing an existing database state. The paper concentrates on structural models provided by UML class diagrams and OCL invariant constraints. We discuss how changes in association multiplicities can be extended to further integrity constraints attached to a class diagram and how these changes interact with given database states.
