Congressman, Constituents, and Contributorscomponent, extends the functionality of the filter. An analysis of our filter and comparisons with compiled filters, in particular for the case of selections and semi-joins, shows the superiority of the direct filter in various situations. These two operations are very useful in a relational database machine.

The Equi-Join Operation on a Multiprocessor Database Machine: Algorithms and the Evaluation of theirRDM. This study shows, among others, that for a given MIRDM configuration; the overall best performing equi-join algorithm is not unique and different algorithms score the best performance depending on the characteristics of the data participating in the equi-join operation.

Some Additional Effects of Contributionsted architecture. It will be shown that this model is capable of exploiting the potential I/O bandwidth of a large number of disk units as well as the computational power of the associated processors.

Francine J. Bigras,Steve J. Colombocycle searching and lengths of cycles are presented. The simulation series are driven by synthetic transaction workloads and also by a real reference string. Finally, the impact of these results on the selection of a suitable concurrency control method for practical applications is discussed.

Workload Modeling for Relational Database Systemsabase machines..The proposed methodology may also be valuable in database design, both at the physical and at the logical level. In fact it allows to compare on a quantitative basis different logical schema for the same application, and suggests the appropriate actions to improve the hysical data organization.

This paper describes design decisions concerning Delta’s architecture and processing algorithms, as well as its overall functions. Delta is expected to be operational with a data storage capacity of 20 GB by March, 1985.
