The report describes fundamental concepts, needs and requirements of a database management system for design optimization. Type of data needing management are identified. A preliminary database management system for structural optimization has been designed, implemented, and evaluated. Detailed specifications for a desirable database management system for more general design optimization environment have been developed. Some important specifications for the system are 1 data independence, 2 multiple logical views of the data, 3 memory management, 4 matrix operations utilities, 5 query language for use in interactive sessions as well as applications programs. and 6 management of permanent, temporary, global and local databases. Such capabilities must be available for design optimization applications. A comprehensive review of literature on database management systems for engineering computations has been completed. It is noted that the field is fairly new. Some systems have been developed in the recent past. Their favorable features and limitations are identified. Based on these studies, development of a comprehensive engineering database management system has been in progress. The system is being developed and integrated into design optimization methods. It will become a core for design, implementation and evaluation of databases for engineering optimization applications.
