An approach for synergically carrying out intensional and extensional integration of data sources having different formats

Abstract

In this paper we propose a data source integration approach capable of uniformlyha ndling different source formats, ranging from databases to XML documents and other semi-structured data. The proposed approach consists of two components, performing intensional and extensional integration, respectively; these are strictly coupled, since they use related models for representing intensional and extensional information and are synergic in their behavior.
