Based on ontology approach to integration of relation databases

This paper is devoted to a problem of integration of relational databases. We consider main structural and lexico-semantic distinctions in representation and the description of the information of relational data which complicate integration. Distinctions in names of objects of databases are most a challenge at integration of relational data. Representation of structure of a database, subject domain and language of the description in the form of ontology can solve this problem. We offer such representation of ontology which divides the procedural knowledge independent of structure of integrated databases and descriptive knowledge, depending from their structure.
