Seminar Report on Distributed Database Management System

Introduction to Seminar Topic on Distributed Database Management System:

Distributed database has become wide spread due to the growing requirement in the data base management systems. In order to increase the response times of the systems the distributed database is employed. Distributed database is the best method for handling the data in the network and it reduces the load on the single server. A central control will be present to organize the distributed data. In this paper we will see how the data gets distributed over the network and how they are used when they are required.

Brief into the distributed database:

In the distributed database the entire data will not be connected to a single cpu they get distributed over the entire network. The operations occurring on the network gets distributed when the application tasks run. This design uses a distributed processing architecture for running the front end and back end tasks.

By the distribution database the user will be transparent and cannot know the physical location of the data. The central link between the user and the distributed data is a database link, which allows the user to access the logical database.

Advantages and disadvantages:

Distributed database increases the reliability and the availability of the databases. As the data gets distributed in the network the response time gets improved. By employing the distribution database we can perform continuous processing of the data. It does make the make the users to rely on the central site for the databases. As the data gets distributed over the network it becomes complex to provide security to the distributed data.
