QMaxUSE: A Query-based Verification Tool for UML Class Diagrams with OCL Invariants

QMaxUSE is an automated verification tool that is able to verify consistencies of a UML class diagram annotated with OCL invariants. QMaxUSE has two distinct features: (1) A query language that allows users to select parts of class diagram to be verified. (2) A powerful algorithm that is capable of performing concurrent verification on large number of complex OCL invariants. This is achieved by decomposing a large model into multiple queries.
