Towards a model for persistent data integration

Abstract

Tool integration in software development environments is a major problem, on one hand, for users of these environments, and on the other hand, for tool builders and suppliers. In this paper, we focus on persistent data integration, which is one of the two main points of tool integration. The purpose of this work is to provide a formal data model that includes most of the semantics of the data manipulated to answer problems raised by persistent data integration. To achieve this goal, we introduce a classical data model, and provide a set of operators which are given for the object transformation. We also provide an example describing the transformation process.
