Title: ENTITY-BASED DATA BASE MANAGEMENT SYSTEMS
Abstract: "A data base management system (DBMS) which supports one of the three popular data models (hierarchical, network and relational) uses a record-based technique for implementing a data base design. This is advantageous when the data being stored is homogeneous, but the technique is not as well suited towards implementing data bases with particularly diverse properties and data types. An alternative technique, the entity-based technique, is presented which allows the design of the data base to be described and implemented as entities and relationships.
The entities and relationships may be presented to a DBMS which will have the capability of deciding whether to store them as individual entities or group them into records. The advantages of defining and maintaining the conceptual view of the data base with entities and relationships are discussed and examples are given to illustrate these advantages.
A system to support the entity-based design technique can be implemented in two ways: (1) Write an interface to an existing data base management system; (2) Implement a data base management system explicitly for the entity-based technique. A set of primitive binary relations is presented which will support the concept of entity-based design. By implementing procedures to create these primitive relations, an entity-based design may be stored and populated as a data base. Algorithms for implementing such procedures for both the above mentioned cases are included.
Also presented are several examples of traditional data base applications and how they might be implemented using the entity-based technique. In addition to the traditional applications, the entity-based technique can support new applications. There is currently much activity in research concerning knowledge representation in Artificial Intelligence (AI) applications. An example is given showing that the entity-based technique is flexible enough to support many different knowledge representations. By using this data base design technique, the AI researcher has available the features and capabilities of a data base management system. An interface to define the knowledge representation to the DBMS is presented and an example using the interface is given."
