= Parallel DBMS is for: - High Performance - High AvailabilityBut both PDB&DDB need to consider the following problems: 1. Data Distribution (Placement & Replicatioin); 2. Query Parallelization(Distributed Evaluation). And also, many parallel system consists of network of workstation, the differ...
The maturation of database management system (DBMS) technology has coincided with significant developments in distributed computing and parallel processing technologies. The end result is the emergence of distributed database management systems and parallel database management systems. These systems have beco...

Even today there are large distributed systems with SMP nodes who in total run adistributed database system. - In the near future, we will find SMP structures on processor chips, complete with partitioned caches, shared higher-level caches etc.. ...
To use RDMA, parallel database systems need to choose between message-passing mechanisms or shared memory abstractions for data transfer. Message-oriented communication is cooperative: The receiver initiates the communication and specifies a location in its memory space that will be changed; then the ...

We begin by describing areas where parallelism is potentially important in dealing with very large databases, including loading, query/update, and database administration. We then discuss hardware tradeoffs, including multicomputers versus multiprocessors, distributed versus centralized memory, and specialised...
This paper describes a computer-cluster based parallel database management system ( DBMS ), InfiniteDB, developed by the authors. InfiniteDB aims at efficiently support data intensive computing in response to the rapid growing in database size and the need of high performance analyzing of massive ...
