[ad_1]Zetmagazine - Central Database is a collection of information in one location that can be accessed from various points, in contrast to a distributed database where information is spread across multiple sites. There are advantages and disadvantages to this arrangement that can be taken into consideration when people make decisions about how to configure a database. This is important to think about when preparing a new database or strengthening a database to meet new needs.
There are several ways to set up a Central database. Some programming languages are suitable for building databases and companies can also buy Database software instead of developing it themselves. Users can have a number of ways to access material, and databases can be set with various levels of security to allow more access control. Information technology staff maintain databases with various operations to keep them neat and deal with early signs of problems such as virus infections. They can also change access levels on request and manage security systems.
One advantage of the Central database is the ability to access all information in one location. Database search can be fast because search engines don't need to check multiple locations to return results. Information may also be easier to organize in one location. In updating the Database to handle more information, the server can be added to the Database site easily, and the company does not need to balance the needs of the distributed database.

Central databases can also be more easily secured physically. This can be covered in various ways to protect it from theft, sabotage, fire, and other problems. It is also possible to create a very strong computer security system to prevent illegal access. For very sensitive databases, computers may not be connected to the network, and users must physically enter the location of the database to retrieve information. This is commonly used by some government computers that contain high security information.
There may also be disadvantages. Central databases tend to create bottlenecks if many users need to access them and their needs are very large. It can also be very vulnerable if something happens to it and the backup hasn't been done or the existing backup is outdated. One of the advantages of distributed databases is the redundancy factor, which can allow the system to function even if the individual database is down.
