In distributed databases, a local and global transaction can be transformed into distributed database systems In parallel databases, the data is partitioned among various disks so that it can be retrieved faster. In distributed databases, query processing and transaction is more complicated in distributed database systems In parallel databases, it’s not applicable.

In parallel databases, query processing and transaction is complicated. The main difference between the parallel and distributed databases is that the former is tightly coupled and then later loosely coupled.ĭifference between Parallel and Distributed databases :ĭistributed Database In parallel databases, processes are tightly coupled and constitutes a single database system i.e., the parallel database is a centralized database and data reside in a single location In distributed databases, the sites are loosely coupled and share no physical components i.e., distributed database is our geographically departed, and data are distributed at several locations.

The sites are linked by a communication network.

There may be a replication of fragments.

It divides large tasks into various other tasksĪ Distributed database is defined as a logically related collection of data that is shared which is physically distributed over a computer network on different sites.

The parallel DBMS link a number of smaller machines to achieve the same throughput as expected from a single large machine.
