An Integration Method for Design Schemas

The complexity of databases is increasing continually. The work of several designers become necessary. Therefore it is interesting to improve the design process with a new phase devoted to information integration , in order to take into account the designers'viewpoints. In this paper, we present an integration process which allows similarities to be discovered between the schemas under study. It works on object-oriented schemas. Whenever possible, we propose several results for the integration of two given schemas. This then makes it possible to choose the one which is the best adapted to the working context, amongst the result schemas. When design schemas are being integrated, the structural, but also and above all, the semantic part of the schemas are studied. To represent the semantic of the words which are used in a schema, we have deened a model of thesaurus drawn from the domain dealing with the meaning of words : linguistics.
