The InterBase system, which integrates preexisting systems over a distributed, autonomous, and heterogeneous environment using a tool-based interface, is described. It supports heterogeneous applications without violating the local autonomy of component systems. The InterBase system locates and starts remote services, transfers and transforms data among(More)
Existing and well entrenched hardware and software systems are the product of lengthy and individual developmental histories. The introduction of harmonious cooperation among such systems carries the potential for great increasea in productivity and improvement in applications processing. However. the utilization of these heterogeneous components is(More)
1 Introduction The computing environments of most organizations currently consist of distributed, heterogeneous, and autonomous hardware and software systems. Previously , these systems ran in isolation, supporting their individual applications. However, decreasing network costs made the connection of these distributed systems feasible, and it soon became(More)
Acknowledgements InterBase These tutorial notes are based on the March issue of the IEEE Data Engineering with the same title and edited by the same author. It is also based on an upcoming book with the same title due to come out later this year and published by Morgan Kauffmann. Thanks are due to Dr. Won Kim of UniSQL for enticing me to organize the(More)
For many applications, a distributed system is an attractive alternative to a single system because it supports global applications accessing multiple systems, and thus enhances performance. The rapid growth of advanced applications involving distributed transaction processing has resulted in the development of various distributed models and languages.(More)
1 Introduction Like many companies with distributed applications, the computing environment at Bell Northern Research (BNR) Inc. is a collection of heterogeneous software packages and hardware platforms. The BNR network includes IBM mainframes and workstations scattered across the U. S., Canada, Great Britain, and Japan. As computing resources have been(More)
