The Object Databases Transformation

This article deals with the transformation of a relational database to an object database. It suggests a new solution based on database and model-driven engineering integration. In the first part it is discussed in general issues of relational database transformation into object one, some problematic areas are identified. Subsequently, depending on detailed analyze of the database reverse engineering processes, the whole process is defined as a sequence of models and transformation among them based on model driven architecture (MDA). Some of the models are based on generally accepted standards. The proposed approach comes also with its own models. The paper defines not only their exact structure but also abstracts its own algorithms used during their development. The final part contains an experimental verification of the proposed procedures with a particular example and summary of the results.
