This paper describes the currently operational version 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 dell'Informazione of the National Research Council and it is running on the HP 21MX computer. It has a decision table interface to enable the user to specify requests and data manipulation commands without the aid of a programmer. The DETAREL system, in addition of being a stand-alone data base management system, gives the basis for the HP 21MX to be a node in a distributed data base.

Abstract
This paper describes the currently operational version 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 dell'Informazione of the National Research Council and it is running on the HP 21MX computer. It has a decision table interface to enable the user to specify requests and data manipulation commands without the aid of a programmer. The DETAREL system, in addition of being a stand-alone data base management system, gives the basis for the HP 21MX to be a node in a distributed data base.| File | Dimensione | Formato | |
