ABSTRACT

DB85, a relational database management system on a minicomputer Interdata 85, is described. It is a single user system to run on a computer with 64K bytes of memory and disk storage. The system supports a high level, relation-algebraic query language which provides facilities for users to define, create, manipulate, and interrogate the relations in the database. Emphasis in the presentation is on the query language design, physical structures of relations, and minicomputer related issues. The approach used in the implementation reflects a clear separation of the logical view and the physical representation of the database. The goal of the project is to investigate minicomputer oriented database technology and to develop a training tool for teaching database concepts.
