Abstract This paper presents the schema and component architectures of a prototype multidatabase management system, EDDS, which is used for research and teaching purposes in the authors' laboratories. Many of the features are shared with other distributed database management systems but some novel features, such as the gateway feature which allows personal computers to share distributed database functionality, are particularly attractive in many of the specific real-world scenarios for which the system was designed. The system is written in C on Unix, and in PASCAL on DEC VMS, and several PC ports have been implemented.
