A FORTRAN System for Flexible Creation and Accessing of Data Bases ; CU-CS-052-74

This paper discusses the implementation of a data base management system designed to enable easy, flexible, data access from FORTRAN programs. The system was created in response to the need for a library of routines for accessing an archival data base whose structure is only tentative and is expected to change frequently and perhaps radically. A FORTRAN library interface between user programs and data bases is described. A methodology for conveniently restructuring data bases without having to change the FORTRAN programs accessing the data bases is presented. This paper also describes a system for restoring and then accessing a data base which has been saved in an obsolete format without having to alter any of the data accessing programs
