Data Base Design.

Abstract

In the four principal activities of data base design, (1) Identifiers and descriptors must be grouped together to form logical records. A suggested standard form and procedure for obtaining this form are described. (2) Relationships among logical records must be established by logical access paths. The hierarchical, CODASYL DBTG, and relational models and the situations in which they are applicable are described. (3) The physical form of records must be determined. Several techniques for reducing storage requirements are described. (4) The physical realizations of logical access paths must be determined. A general technique is described, examples are presented and evaluated, and specific suggestions are made for many different types of applications. (Author)
