Abstract
Verifying whether a UML class diagram is consistent involves finding valid instances that provably meet its
constraints defined in Object Constraint Language (OCL). Recent studies have shown that many existing tools and techniques
not only can find valid instances but also pinpoint the conflicts among the OCL constraints. However, they do not scale well and
are often unable to locate the conflicts when the number of OCL constraints significantly increases. In this paper, we present a
novel approach that is capable of verifying UML class diagrams with a large number of OCL constraints. Our approach has two
distinct features: (1) it provides a query language that allows users to choose parts of a UML class diagram to be verified. (2)
a new algorithm that can handle an extreme size of OCL invariants via concurrent verification. We have implemented a new
automated tool called: QMaxUSE. The evaluation results suggest that QMaxUSE has the potential to be adapted by industry
and offers up to 30x efficiency improvement in verifying UML class diagrams with a large number of OCL constraints.
