Mediation is an approach that allows integrating different heterogeneous, distributed and scalable data sources. The objective of our paper is to define an approach of mapping, one of the essential operations that can describe and define the set of links between the two levels of mediation system: mediator schema (global) and schemas of sources to be integrated (local). Our approach allows to define...
Data integration involves combining data residing in different sources, and providing the user a unified view of this data. The problem of designing data integration systems is important in current applications of the real world, and the question which arises at the mapping is how to link the global schema and the set of local schemas of sources. In this paper, we present our approach of mapping for...
Data integration involves combining data residing at different sources, and providing to the user a unified and global view of this data. The problem of designing data integration systems is important in current applications of real world, especially for mapping between attributes of global schema and those of local schemas of sources. The question is how to link the global schema and the set of local...
