Abstract

Triple Graph Grammars are a well-established, formal and intuitive concept for the specification and analysis of bidirectional model transformations. In previous work we have formalized and analyzed already termination, correctness, completeness, local confluence and functional behaviour.In this paper, we show how to improve the efficiency of the execution and analysis of model transformations in practical applications by using triple rules with negative application conditions (NACs). In addition to specification NACs, which improve the specification of model transformations, the generation of filter NACs improves the efficiency of the execution and the analysis of functional behaviour supported by critical pair analysis of the tool AGG. We illustrate the results for the well-known model transformation from class diagrams to relational database models.
