Abstract

Sharing and integrating information among multiple heterogeneous and autonomous databases has emerged as a strategic requirement in modern enterprises. We deal with this problem by proposing a declarative approach based on the creation of a reference model and perspective schemata. The former provides a common semantic, while the latter connects schemata. This paper focuses on deduction of new perspective schemata using a proposed inference mechanism. A proof-of-concept prototype, based on Logic Programming, is presented in brief.
