Visual Models Transformation in MetaLanguage System
At the process of creation and maintenance of information systems the model-based approach to the software development is increasingly used. This approach allows to move the focus from writing of the program code with using general purpose language to the models development with automatic generation of data structures and source code of applications. However at usage of this approach it is necessary to transform models constructed by various categories of users at different stages of system creation with usage of various modeling languages. An approach to models transformation in DSM platform MetaLanguage is considered. This approach allows fulfilling vertical and horizontal transformations of the designed models. The Metalanguage system support “model-text” and “model-model” types of transformations. The component of transformations is based on graph grammars described by production rules. Transformations of model in Entity-Relationship notation are presented as example.
