Abstract

Basic concepts of relational data base management systems are described. Characteristics of the relational approach are identified and compared with present implementations of hierarchical and network data base systems. Depending on the application, a user may experience one or more of the following benefits of relational systems described in this paper: ease of understanding, increased data independence, ease of use, sound theoretical basis, and generalized data definition. Types of applications most suited to hierarchical and network data base systems are also compared and contrasted.
