ABSTRACT
Parallel database systems are being used nowadays in a wide variety of systems,
right fromdatabase applicationsto decisionsupportsystems.These implementations
involve database processing and querying over parallel systems. For the parallel
databases to be effective and efficient, various optimizing solutions need to be
implemented. These solutions dealwithvariousissues associatedwithsuch database
systems : query optimization, data allocation within the database, etc.
This paper will attempt to give the reader an understanding of the various issues
involved in optimizing the performance of a parallel database system. The primary
areas offocus will be systemarchitecture, query optimization and data reallocation.
It will look at related work done by other authors in this field and hopefully provide
a thorough understanding of the solutions in this area.
