Abstract

An information integration system provides a uniform query interface for collecting of distributed and heterogeneous, possibly autonomous, information sources, giving users the illusion that they interrogate a centralized and homogeneous information system. One approach that has been used for integrating data from multiple databases consists in creating integrated views, which allows for queries to be made against them. Here, we propose the use of Correspondence Assertions (CAs) to formally specify the relationship between the integrated view schema and the source database schemas. In this way, CAs are used to assert that the semantic of some schema’s components are related to the semantic of some components of another schema. Our formalism has the advantages of proving a better understanding of the semantic of integrated view, and of helping to automate some aspects of data integration.
