Parallel DBMS

General objective of this lecture is to describe on Parallel DBMS. Parallel database systems combine database management and parallel processing in order to deliver high-performance and high-availability database servers at a much lower price than equivalent mainframe computers. Here also briefly explain on Functional Aspects provided by parallel database systems and Parallel Architectures. This lecture briefly focus on three basic parallel computer architectures depending on how main memory or disk is shared: Shared-memory, Shared-disk and Shared-nothing.
