Implementation of an efficient run-time support system for engineering design environment

Abstract The need for both relational and matrix data types in engineering applications has been long recognized. While matrices form mostly temporary or semi-permanent data private to a program, relations are either permanent data in public domain used by different programs or final results of a program to the end user. Though several systems came up in the last few years with various degree of facilities and level of efficiency, none however, met the requirement of versatile data structure or run-time support required in a volatile, large I/O environment of engineering database. This paper describes implementation of a system and its evaluation using an existing users' interface. Benchmarking shows that the system is far superior to the existing ones and also incurs little overhead for DBMS calls.
