A Federated Layer to Integrate Heterogeneous Knowledge

The way developers define architecture, execute architectural strategy, and record the results make a critical difference in the ability to deal with information and knowledge. In this context, integrating databases is very important indeed, but the different semantics they possibly have usually complicates administration. Therefore, recovering information through a common semantics becomes crucial in order to realise the full knowledge contained in the databases. In this paper, we describe and illustrate a proposal on the use of layered architectures to integrate knowledge from heterogeneous sources. We illustrate how the process might be facilitated by applying ontology-based comparisons as part of the components' behaviour.
