REMOTE DATABASE ACCESS IN THE DISTRIBUTED COMPUTING ENVIRONMENT

This paper describes the design, implementation and testing of a set o f software modules that are used for remote database access in a distr ibuted computing environment. The goal of our research and development is to implement a client server model using Structured Query Language (SQL) functions in the Open Software Foundation's (OSF) distributed c omputing environment (DCE). This design is compared with another which simply uses the sockets application programming interface (API), runn ing over the transmission control protocol/internet protocol (TCP/IP), and is implemented in subroutines that act similar to the remote proc edure call (RPC) generated stub code. The prototypes for the remote SQ L access project are implemented using an IBM RISC System/6000 (the cl ient) running the AIX operating system and an IBM AS/400 (the server) running the OS/400 operating system. We selected the AS/400 for its da tabase abilities, and the RISC System/6000 since the DCE software is a vailable for it.
