DETAREL : a generalized minicomputer relational data base management system

In this paper we discuss the design and implementation of a mini computer relational data base management system: the Decision TABLE RELATIONAL system (DETAREL). DETAREL is a generalized data base management system based on_Codd's relational model of data. It is designed and implemented at the Istituto di Elaborazione della Informazione of the National Research Council and it is running on the HP- 2100F computer. It has a decision table interface to enable the uset to specify requests and data manipulation commands without the aid of a programmer. All the facilities are integrated in one high level user oriented language. The DATAREL system, in addition of being a stand-alone data base management system, gives the basis for the HP 2100 computer to be a node in a distributed data base.
