Transforming Relational Model Queries to Triple Graph Grammars

Views are an important part of model-driven development processes, as they allow developers to work on abstractions of potentially complex system models. The definition of model-view transformations is, however, difficult, especially if bidirectional synchronization between models and views is required. In this work, we present a relational operator model for specifying queries on heterogeneous models, as well as a transformation of our operators to triple graph grammars. View definition approaches can use our operator model as transformation backend and leverage the inherently bidirectional and incremental transformation operationalization of triple graph grammars. We further present an initial evaluation using a prototype implementation of our operator model and transformation, and discuss possibilities to extend the operator model.
