What is a Distributed Database Management System?

distributed database system

Simply a distributed database management system (DDBMS) is the software that manages the distributed database and provides an access mechanism that makes this distribution transparent to the users.

A distributed database system is the union of what appear to be two diametrically opposed approaches to data processing. This binds database system and computer network together.

There are different types of database and network model. Along with that database is much more required in data management.

Simply a distributed database is a database in which not all database or collection of databases or storage devices are not attached to a comment processor. It may be stored in different computers or multiple computers, located in the same location or different network location.

Traditional Database Processing or Filing Model

Here we can see all the programs have different data description storage and they will be linked to different files and for normalization, it also has a redundant data platform. Here we can see at one place there are so many things are happening.

Now here we need to understand about the distributed data processing.

What is Distributed Data Processing?

This can be generally referred to as a distributed computing or distributed data processing. Some degree of distributed processing goes on in any computer system even on single-processor computers where the central processing unit (CPU) and input/output (I/O) function are separated and overlapped. This separation and overlap can be considered as one form of distributed processing.

Generally we can say that a distributed computing system is a collection of autonomous processing elements that are interconnected by a computer network. The elements cooperate in order to perform the assigned task.

Here in distributed processing, we are distributing the processing logic. The definition itself says that processing logic or processing elements are distributed to get things done.

Now we really need to know about what is a distributed database system.

What is a Distributed Database System?

Distributed database is a collection of multiple, logically interrelated database distributed over a computer network.

So here DDBMS is a software that helps to mange the distributed database as we have already defined in the beginnging it provides access mechanism.

All the databases are logically interreleted and distributed over computer to make it more transparent to the users.
