Function request shipping in a database machine environment, which implement the transaction must somehow come to exist at the necessary sites; they must be linked and loaded; and each must be invoked by a coordinator or subordinate transaction thread. We call this mechanism function request shipping, or FRS. The primary concerns in FRS are about the code th

An experiment on response time scalability in Bubba,s increased. We further show how these effects change under increased levels of concurrency and heterogeneity in the transaction workload. From the results, we conclude that although parallelism must be limited in some circumstances, in general the benefits of increased parallelism in shared-nothing systems exceed the costs.

Special function unit for statistical aggregation functions,oposed unit is considered. The performance of the proposed design is compared with the implementation of statistical aggregation functions on the parallel pipelined relational query processor described in [1]. The comparative analysis shows that our approach performs significantly better than that of [1].
