Abstract:

In this report, the research completed under the project in the area of database management in engineering design and optimization is described. Database management concepts used in business applications were studied and concepts suitable for engineering applications were developed. Data structures that need to be managed were identified. Database design methodologies were studied and a suitable methodology for engineering designs and optimization applications was developed. Several prototype database management systems DBMS were designed, developed and evaluated. Several prototype application programs utilizing a database management were developed to evaluate performance of DBMS. Based on these implementations and studies, the usual relational data model was generalized to handle engineering data types. Specifications for an integrated DBMS capable of handling relations, vectors and matrices of different types were developed. A system based on the specifications, called MIDASGR was implemented and evaluated. MIDASGR stands for Management of Information for Design and Analysis of SystemsGeneralized Relational Model.
