MULTIBASE -- A Research Program in Heterogeneous Distributed DBMS Technology.
Abstract
This report describes the architecture of the Multibase system. Details of the components of the architecture to be implemented in the initial breadboard version are also described. Although additional research is requierd to fill in the details of optimization and incompatible data handling, the architecture already contains several innovative ideas in integrating distributed heterogeneous databases. These include: the idea of using an integration data base to resolve data incompatibility; the idea of using a mapping language to uniformly define the global schema in terms of the local schemata and the integration schema; and the idea of using query modification and query graph decomposition to transform a global query into local queries and queries over the integration database.
