Abstract Data base management systems have grown rapidly in their power and complexity over the 15-year history of data processing on commercially available computers. The original concepts have split, and new terms have been adopted to name and refer to these concepts. The Data Structure Diagram graphic technique is used to illustrate the splitting of the concepts and the structural relations which exist between these concepts at each point in the evolution.
