Query Processing in Distributed Heterogeneous Databases,

Abstract

In order to bring distributed heterogeneous DBMSs which are implemented with relational, CODASYL or hierachical models together to share the information resources and build new kinds of applications, we propose to use relational model as global conceptual model and ALPHA as global nonprocedual high-level query language. We described the distributed query processing scheme in this environment. A scheme translation and query translation for CODASYL system case are discussed. Relational and Hierachical systems can be treated similarily.
