The thin client technology also provides server-based computing facilities to companies (Kumar 2007). There is a browser terminal or a central server from which all other computers can access required information, as well as can do required work through sharing. Companies can use either standalone or wireless thin clients to run their business processes. The purpose of technology is to facilitate businesses by reducing the total cost of ownership and providing easy and efficient usage. The main advantages of using think clients are security, efficient use of resources, and low cost (Kumar 2007). The main disadvantage of this technology is that is not designed for heavy tasks.

“A distributed database is a database that is split over multiple hardware devices but managed by a central database controller” (Holmes n.d.). A distributed database means the division of a database into different physical units separated by a business or geographical region. Some of the main advantages of using distributed databases in business include better control of resources and improved business performances. However, the risks associated with the data integrity of distributed databases include the accuracy of stored data and the risk of unauthorized access to spoil or alter the stored data.

The first strategy that can be used to overcome such risks includes double-checking the database for database integrity, domain integrity, and referential integrity before and after making changes to the data. The second strategy is using authentication of the people trying to log on to the network. Using this feature, only officials are provided with passwords and biometrics that they can use to prove their identity, as well as to make secure use of the distributed network. Authentication is done to make the network safe by stopping and preventing unauthorized attempts to the network. ...Download file to see next pages Read More

Databases Introduction A distributed database (DDB) is a compilation of numerous, logically interconnected databases distributed through a computer system. Distributed and parallel processing is a well-organized way of enhancing performance of DBMSs (Data-Base Management Systems) and systems that control large volumes of data (Abuelyaman, 2008). The main concern of DBMS structure is the partitioning and allocation of the fundamental hypothesis partitioning techniques. This paper seeks to find a suitable distributed database that can fit two small retail stores. A partitioning scheme This paper recommends a scheme for vertical partitioning of a distributed database. Vertical part...

DDBMS versus a Decentralized Database Insert Insert Introduction A distributed database management system manages a distributed database. That is a database whose storage is in multiple computing systems that may or may not be in the same location. Consequently, the work of the DDBMS is control such a database as though it was working in the same place (Moris, February 4, 2014). The purpose is to synchronize the data and ensure that actions like updates are in all other areas in case of multiple users. Decentralized database, on the other hand, is an example of a massive database being divided into smaller ones. It is done so that an individual data subject is represented by a sma...
