The document discusses a parallel database system project by group members Md Momtasin Tanvir, Amee Patel, and Rajdeep Singh. A parallel database system uses multiple CPUs and disks to boost processing and input/output speed by parallelizing operations. It is suitable for online transaction processing and decision support systems that require analyzing large amounts of data in real-time. The benefits of parallel databases include speed, reliability, and capacity to handle large volumes of requests, though they require extensive resources that increase costs.

2. Definition of Parallel Data Base
System:
 Parallel Database system is a process where
data management works occur in a
multiprocessor computer through parallelization
of different operations.
 By Using multiple disk and CPU this system
boost processing and input-output speed.
Some popular uses of parallel data
base system nowadays:

3. Cont..
 Online transaction processing (OLTP):
On OLTP process multiple transaction need to be
done in real-time, so parallel database system is
suitable for it.
 Decision support system:
In decision support system a massive amount of
data can be analyzed and compiling of information
can be done as well. For these parallel data base
system is highly needed.

4. Some benefits :
 Speed:
The principle benefit of this database is speed.
The server breaks user database request into
different parts and send them in different computers
for processing which gives very high speed.
 Reliability:
This database system can continue to work despite
the failure of any computer.
 Capacity:
With more user request this system increase the
uses of computers, so huge amount of request can
be handled.

5. Some problems related with this
system:
 Extensive amount of resources are required to
support parallelism.
 More resources will increase cost.
 Processor’s waiting time will increase due to more
processors.
Future Uses of parallel database
system:
 According to the past 20+ years trends it can be said
that parallel database system is the future of
computing because of recent development of fast
network, distribution system and multi processor
