A database management system, also called a DBMS, allows users to create a new database by specifying the logic structure of the data. For instance, the world of interest is represented as a collection of tables in relational DBMSs. This simple model is useful for many applications, and ...

In many systems the parallel-related parameters are left at their defaults, so the limit that gets reported usually matches the parameter cpu_count (because the parallel_threads_per_cpu is often 1, and the system is not often RAC in which the limit is also scaled up by the number of inst...
by the advances in parallel database systems [26]. These systems exploit recent multiprocessor computer architectures in order to build high-performance and high-availability database servers at a much lower price than equivalent mainframe computers. Note that performance was also the objective of the...
