Abstract

In this paper we present DIKE, a system supporting the semi-automatic construction of cooperative information systems from heterogeneous databases. The input of DIKE consists of the set of databases to belong to the cooperative system. First, DIKE constructs a data repository representing a structured, integrated and consistent description of the information stored in the input databases. The data repository thus constructed is then used as the core structure of a mediator-like module supporting the user-friendly integrated access to available data resources. The core of DIKE is the extraction and exploitation of the inter-schema knowledge (in the form of inter-schema properties) relative to the involved database schemas.
