Abstract:
The automation of the database design process using CASE tools is among the multiple efforts devoted to face the problems of database modeling. These tools often do not take into account all information presented in a conceptual schema. Consequently, the relational elements obtained during these processes do not coincide completely with the conceptual elements, and that produces some semantic losses. The idea is to enrich these tools and to improve them in order to solve some problems of modeling. The goal of this work is to propose an efficient approach to generate mechanisms that preserve the participation constraints during the transformation of a conceptual schema into a relational one.
