Advantages Of Centralized Database

Databases today are essential to every business. Whenever you visit a major Web site – Google, Yahoo!, Amazon.com, or thousands of smaller sites that provide information – there is a database behind the scenes serving up the information you request (Hector, Ullman, & Widom 2008). Database systems are becoming as common in the workplace as the essential one that it can easily be searched, categorized and recalled in different means that can be easily read and understood by the end user.

When geographically dispersed organization, you may choose to store them Databases on a central database server, or to be distributed to local servers (or A combination of both). A distributed database is one logical database that is Spread across computers physically in multiple locations that are linked by Network data connections. We emphasize that a distributed database is really A database. Distributed database is still Centrally managed as a resource to provide local companies with flexibility And customization. The network must allow users to exchange data. And thus the user (Or program) in place A must be able to access (and possibly update) data in Place B. site had spread sites spread over a wide area system that shown in figure below

Increased reliability and availability: A distributed database system has multiple nodes (computers) and if one fails then others are available to do the job. So we can say that redundancy and replication of the DB increase security and accessibility.

atabase is a collection of data which describes the activities of one or more organizations in a well-defined structure and the structure of a database is specific and it has a purpose. Database Management System (DBMS) is used to control or organize the data in a database. Database Management System (DBMS) is also used for maintaining large collections of data. Distributed database can be defined as a collection of various databases which can be stored at different computer network locations. In this paper we discuss about Distributed Databases, their advantages and disadvantages.

-Lower cost. NAS systems are inexpensive and have capacities that are cheap as low as 1 or 2 TB. This allows small and medium business’s to use the system

Availability - Data and information systems are available when required. This ensures the network will be availability.

Fault tolerance may be the most important for an organization, when a system fails the organization is venerable to loss of data and fault tolerance and a backup plan for disaster, would implement services of no loss at all. This is provided by the proper fiber optic wiring to a storage server with duplicates of all

Also by these systems the company reduced its business cost and maintains the information and the data very updated form.

It eliminates redundancies which enhance the security and makes things happen in a faster, cheap and efficient way.

* More frequent face to face communication , written / electronic communication- lower operation costs.

Distributed database is the study of how the communication can be build by creating the data on the local computer and distributed that information on different computer connected to the same physical loacation. With the involation of the Distributed database in the rapid growth of the Internet can

Furthermore, this type of server does not require a great deal of maintenance. It is easily identifiable both physically and on the company's network, since the data is stored in a single

Making sure that the Database (DB) has online access 24/7 in order for the data to be updates and as well as sync all the time.

* Real time access over CDAS- It can reduce the time that will take to ask special requests on IS support. By having real time access, analysts can analyst consumer data more effectively.

Another benefit is that it allows the office to operate in a smaller environment, because a great deal of space is not required for storing documents in a paper filing system.
