Abstract
This paper deals with database management concepts in computer-aided design optimization. Complex nature of engineering data and the need to organize them are emphasized. Database management concepts applicable to finite element analysis and design optimization are explained. Various aspects associated with the development of data models, such as conceptual, internal and external models are discussed. Suitability of external models, like hierarchical, network and relational, are discussed with reference to design optimization requirements. Some techniques to organize data of large matrices for efficient numerical computations are given. Concepts of normalization of data, global and local databases are described. Details of a suitable database management system are described in a separate paper.
