A distributed catalog for heterogeneous distributed database resources

Abstract

To support a distributed, heterogeneous computing environment, an inter-system catalog protocol is needed so that remote resources can be located, used, and maintained with little human intervention. This paper describes a scalable catalog framework, which is an extension of previous work in a distributed relational DBMS research prototype called R*. This work builds on the R* concepts to accommodate heterogeneity, to handle partitioned and replicated data, to support non-DBMS resource managers, and to enhance catalog access performance and system extensibility.<>
