Improved performance, Database Management System

Assignment Help:

Improved performance:As the data is located near the site of its demand, and given the inherent parallelism because of multiple copies, speed of database access may be good for distributed databases than that of the speed that is achievable by a remote centralised database. Also, since every site handles only a part of the whole database, there may not be the similar contention for CPU and I/O services as characterized by a centralised DBMS.
