The Raid distributed database system

B. Bhargava, J. Riedl
1989 IEEE Transactions on Software Engineering  
Raid is a robust and adaptable distributed database system for transaction processing. Raid is a message-passing system, with server processes on each site. The servers manage concurrent processing, consistent replicated copies during site failures, and atomic distributed commitment. A high-level, layered communications package provides a clean, location independent interface between servers. The latest design of the communications package delivers messages via shared memory in a

Raid provides the infrastructure to experimentally investigate various methods for supporting reliable distributed transaction processing. Measurements on transaction processing time and server CPU time are presented. Data and conclusions of experiments in three categories are also presented: communications software, consistent replicated copy control during site failures, and concurrent distributed checkpointing. A software tool for the evaluation of the implementation of transaction processing algorithms in an operating system kernel is proposed.
