Heterogeneous Database Interoperability Using the WWW

Gustavo Zanini KantorskiCora H. F. Pinto Ribeiro

The integrated access to distributed heterogeneous information is a major concern in large corporations and governmental institutions. However, integrated access to disperse information should not require the eradication of local systems heterogeneity and autonomy because of the financial impact associated to such solution. The use of available Internet tools turns out as an affordable, simple, and also platform and DBMS independent, alternative for integrated information retrieval of heterogeneous databases. This paper presents a tool for integrated access to heterogeneous databases through the Internet. The proposed solution is supported by the previous mapping of all participant conceptual schemata and by the use of available Internet technology.
