A framework based on model driven engineering to support schema merging in database systems

Abstract

Model Driven Engineering (MDE) aims to make face to the development, maintenance and evolution of complex software systems, focusing in models and model transformations. This approach can be employed in other domains such as database schema integration. In this paper, we propose a framework based on MDE to integrate database schema. In MDE context, database schema are viewed as database model. A metamodel for creating database models, an algorithm for database model matching and an algorithm for database model merging are presented. We provide a prototype that extends the MT4MDE and SAMT4MDE tools in order to demonstrate the implementation of our proposed framework. An illustrative example helps to understand our proposed framework.
