1. A.Avizienis, A.F.Cardenas, F.Alavian: On the Effectiveness of Fault-Tolerance Techniques in Parallel Associative Database Processors, Proc. of Int. Conf. on Data Engineering, Los Angeles, 1984, pp. 50–59. The paper deals with some fault-tolerant techniques which differ from those proposed in [CAA83]. A general model representing machines like CASSM and RAP is described and fault-tolerance is systematically applied to its organization. Storage areas are protected by duplication and error detecting and/or correcting codes. The area processors, which search storage areas, are replicated and periodically checked. The effectiveness of these techniques is shown by the analytic results obtained by a program based on a unified Markov reliability model.
2. R. Agrawal and D. J. DeWitt: Recovery Architecture for Multiprocessor Database Machines, ACM SIGMOD, Austin, Texas, 1985, pp. 131–145. This study deals with recovery and its impact on performance of database machines. The authors propose several parallel recovery architectures for multiprocessor database machines and examine their characteristics in detail; they then evaluate the impact of the results on database machine performance. Log, shadows and differential files mechanisms are examined and performance is evaluated by means of simulation experiments. Two metrics are used for studying the performance: average execution time per page and average transaction completion time. The results indicate that a recovery architecture based on parallel logging has the best overall performance.
3. R. Agrawal: A Parallel Logging Algorithm for Multiprocessor Database Machines, Proc. of 4th Int. Workshop on Database Machines, Grand Bahama Island, 1985, Springer-Verlag, 1985, pp. 256–276. In this paper a recovery architecture based on parallel logging for multiprocessor-cache database machines is presented. Simulation experiments are made in order to determine the characteristics of the parallel logging algorithm and its impact on database machine performance. The author shows how the recovery actions can be completely overlapped with the data page processing so that the performance of the database machine is not degraded by recovery overhead.
4. Amperif Corporation: The Relational Database Machine RDM-1100, Amperif Corporation, 1982, Chatsworth, California. The RDM 1100 was introduced for use with UNIVAC 1100 host computers and Amperif disk drives; it uses the Britton-Lee IDM (see [BRI81]) internally under its cover. Interface software which permits the host computer to utilize the RDM 1100 requires no modification in the UNIVAC operating system. A relational query language provides a high-level, on-line interface to the RDM 1100.
5. J.P.Armisen, J.Y.Caleca: A commercial back-end data base system, Proc. of 7th Int. Conf. on Very Large Data Bases, Cannes, 1981, pp. 56–65. This paper describes the M1X database machine developed for commercialization. The back-end supports both a Codasyl and a relational interface, and locking and recovery mechanisms are included.
