Design and Implementation of a Relational Database Server In a Heterogeneous Network Environment

This paper discusses the architecture and application program interface of a relational database server. A database server provides database access services such as ad-hoc query, database update, database creation, database administration support, etc. These services are provided to multiple application programs running on one or more networks of heterogeneous host computers. A prototype database server consisting of a relational database machine and a front-end query processor was implemented in a HYPERchannel network environment. The requirements and design of the prototype and some initial applications of the database server are discussed.
