Converting to DBMS 20 from Integrated Data Base Management System (IDMS)

摘要

A multi-project procurement system was developed for the Project Procurement and Control Department of the Planning and Control Division, Union Carbide, Oak Ridge Gaseous Diffusion Plant. This real-time system provides Union Carbide with information necessary for budgeting, scheduling, planning, and reporting procurement status to the Department of Energy. The system was initially designed and developed under IDMS on an IBM mainframe. A DEC 2020 was later purchased, and the procurement system was converted from IDMS to DBMS-20. Topics to be covered will include the procedures followed during the conversion, the differences and similarities of the two data base systems, and problems encountered during the conversion.
