Specification for MIDAS-GR. Management of Information for Design and Analysis of System. Generalized Relational Model.
Abstract
This report presents specification of a database management system currently under development. It is specifically designed to meet the requirements of engineering applications. The stress in design lies on the flexibility of data definition capabilities, efficient management of large volume of I/O, and dynamic creation and deletion of data objects. In data definition the system takes unified approach for relational and numerical data models. It also defines a set of frequently used special data types (sparse matrix etc.) and provides uniform data structure for their efficient manipulation. The system also provides powerful data language which can be used directly from a terminal on ad hoc basis or from a host programming language. This language is non-procedural; so for a large class of problems user need not resort to branching or loops. Also, since it is precompiled instead of being interpreted at run time, it is inherently much faster. It is expected that this system will play central role in design and implementation of future systems in design optimization area. (Author)
