Sibyl: a relational database system with remote-access capabilities

ABSTRACT

The proliferation of inexpensive microprocessor systems and communications equipment has provided the general public with the ability to access remote database systems. It also makes off-loading of some of the query-processing load of such remote systems to microprocessor systems an attractive possibility, but problems concerning data portability and adequate software support need to be resolved. To demonstrate the feasibility of such a loose coupling of a microprocessor system with different brands of remote database systems, a relational database system capable of exchanging data with heterogeneous remote systems was designed and implemented. We describe the functionality of this operational system as well as the design and implementation of its major components.
