A general purpose data base design

摘要

One of the major problems facing data base designers is how to develop a logical data base design for a proposed application. Usually, for each new application, a new data base design is produced. For a Data Base Task Group (DBTG) data base management system (DBMS) this means creating a new schema and subschemas. This paper describes a non-volatile data base design that allows the DBTG structure of the data base to remain constant, regardless of changes in the applications it is portraying.
