Abstract
Shifting the focus from code to models in software development brings into view model-related tasks such as querying which are not very well supported by current CASE tools. Existing textual query languages like OCL are often not acceptable for domain modelers. Also, most query languages suffer from a mismatch between models, queries, and results. The Visual Model Query Language (VMQL) tries to overcome this by using a modeling language also as the query language and result presentation language.
