Resource Location in Large Scale Heterogeneous and Autonomous Databases

In many large organizations there has been a proliferation of database systems to handle ever increasing volumes of information. In order to explore a potentially huge on-line information space, we must develop an architecture which allows for the dynamic data driven construction of inter-database node relationships in an incremental manner. In this paper we introduce the FINDIT architecture which uses informationmeta-types to provide a basis for such an organization and, consequently, provides a platform for interoperability. A distinction is made between theinformation andinter-node relationship spaces to achieve scalability. Tassili language primitives are used for the incremental building of dynamic inter-node relationships based upon usage considerations.
