A database management system was designed and implemented for the No. 5 Electronic Switching System. It is a specialized database management system based on the relational data model. The database is distributed and subject to stringent real-time constraints and reliability requirements. The system characteristics, capabilities, and design philosophy are described herein.

This paper identifies six fundamental distributed computer system research issues, points out open research problems in these areas, and describes how these six issues and solutions to problems associated with them transect the communications subnet, the distributed operating system, and the distributed database areas.
Construction and application of barrel finishing underlying database platform
A new database platform for barrel finishing data has been constructed by using database technology and case-based reasoning to ensure the safe and convenient storage as well as the sharing of experimental data of the barrel finishing process.
Operational Switching Systems

Consistency, concurrency, and crash recovery
This paper presents a method for increasing concurrency in shared data bases that allows for convenient recovery from crashes which do not affect the information on secondary storage.
The updatability of relational views based on functional dependencies
This paper describes a constructive approach to supporting view updates for a broad class of views by first identifying a class of view whose interpretations are consistent with the interpretation of the underlying database.
