As its main characteristic, this language allows a user to freely mix graphical and textual formulation of a query. We show how syntax and semantics of this hybrid language are formally defined by means of a slightly extended version of PROGRES, a specification formalism based on programmed and attributed graph rewriting systems."}],"year":"1994","status":"public","intvolume":" 776","publication":"Proceedings of the International Workshop on Graph Transformations in Computer Science (1993), Dagstuhl (Germany)","doi":"http://dx.doi.org/10.1007/3-540-57787-4_2","language":[{"iso":"eng"}],"date_created":"2019-03-04T11:52:13Z","date_updated":"2022-01-06T07:03:52Z","type":"conference","volume":776,"title":"Syntax and Semantics of Hybrid Database Languages","citation":{"ama":"Andries M, Engels G.
