What is a centralized database?

Centralized database is a collection of information in one place accessible from many points, unlike a distributed database, where information is spread in multiple places. There are advantages and disadvantages that can become considerations when people decide how to configure databases. It is important to think about setting up a new database or additional database to meet new needs.

There are many ways to set a centralized database. Multiple programming languages ​​are very suitable for building databases and companies can also purchase database software than develop their own. Users can have a number of material access methods and databases can be set with different security levels to allow more access controls. Information technology employees maintain the database with various operations to maintain it properly and solve premature signs of problems such as viral infections. Can also change the levels of access on request andManage the security system. Finding a database can be fast because the search engine does not have to check multiple seats to return the results. Information can also be easier to organize in one place. In the database upgrade to process more information, servers can be added to the database site easily and the company will not have to balance the needs of the distributed database.

Centralized database can also be easier to physically secure. It can be closed in various ways to protect it from theft, sabotage, fire and other problems. It is also possible to create an extremely robust computer security system to avoid unauthorized access. For extremely sensitive databases, computers may not be connected to the network and users will have to physically enter the location of the database to pull out the information. This can be used on some government computers that contain high security information.

There may also be disadvantages. The centralized database tends to create narrow places if they have to approach multiple users and their needs are considerable. It can also be very vulnerable if something happens and the backup has not been done or the existing deposit is outdated. One of the advantages of distributed databases is the redundancy factor that can allow the system to operate, even if the database is below.
