One of the data services offered within the CORDS Service Environment is a multidatabase. Fulfilling this service requirement is the man date of the CORDS Multidatabase project involving researchers at the University of Waterloo and Queen's University. One objective of this project is to research issues in multidatabase systems. Thus far these include schema integration, (global) query decomposition and optimization, and distributed transaction management. A second objective is to design and implement a multidatabase prototype. The latter objective presented an opportunity to explore and assess a number of international and industry standards: for example, Microsoft's Open Database Connectivity (oDBC) and the Open Software Foundation's Distributed Computing Environment (OSF/DCE).This paper discusses the overall design of the multidatabase, the research issues addressed, and the status of the prototype implementation.
