vGMQL – Introducing a visual notation for the generic model query language GMQL
Steinhorst Matthias, Delfmann Patrick, Becker Jörg
This paper presents a visual query notation for the generic model query language GMQL. So far, GMQL allows for specifying pattern queries as complex set-theoretical formulas. This fact impedes the practical usability of GMQL, because specifying and understanding a query is unintuitive. The visual query notation we propose is a first step towards resolving this shortcoming. We derive objectives for this notation, implement it in a working prototype, as well as evaluate the notation using expert interviews and a literature survey.
