FGAV (Fuzzy Global as Views)

The mediation is an approach of integration, which allows to integrate different heterogeneous, autonomous and scalable sources of information, it provide to the user an uniform access, while hiding the peculiarities of each sources. In this paper, we presenting an approach of mapping for mediation systems, an operation that is used to define and describe all the links between the elements of global schema and those of local schemas. To this end, we firstly presenting our approach to mapping that consist to defining and associates for each link between two elements the weight that reflects the degree of its existence by using an analysis of two components: syntactic and semantic. On the other hand, we integrate a set of functionality for source schemas with elements of complex types.
