Database administration is the function of managing and maintaining database management systems (DBMS) software. Mainstream DBMS software such as Oracle, IBM Db2 and Microsoft SQL Server need ongoing management. As such, corporations that use DBMS software often hire specialized information technology personnel called database administrators or ...
One technique for evaluating database security involves performing vulnerability assessments or penetration tests against the database. Testers attempt to find security vulnerabilities that could be used to defeat or bypass security controls, break into the database, compromise the system etc. Database administrators or information security administrators may for example use automated ...
Formally, a "database" refers to a set of related data accessed through the use of a "database management system" (DBMS), which is an integrated set of computer software that allows users to interact with one or more databases and provides access to all of the data contained in the database (although restrictions may exist that limit access to particular data).
A database administrator (DBA) manages computer databases. [1] The role may include capacity planning , installation , configuration , database design , migration , performance monitoring, security , troubleshooting , as well as backup and data recovery .
Most database management systems are built around one particular data model, although it is possible for products to offer support for more than one model. Various physical data models can implement any given logical model. Most database software will offer the user some level of control in tuning the physical implementation, since the choices ...
Connolly and Begg define database management system (DBMS) as a "software system that enables users to define, create, maintain and control access to the database". [23] RDBMS is an extension of that initialism that is sometimes used when the underlying database is relational.
an overall enterprise architecture that favors shared data models [5] over allowing each application to have its own, idiosyncratic data model. Even an extreme database-centric architecture called RDBMS-only architecture [6] [7] has been proposed, in which the three classic layers of an application are kept within the RDBMS. This architecture ...
One of the most important advantages of application-level encryption is the fact that application-level encryption has the potential to simplify the encryption process used by a company. If an application encrypts the data that it writes/modifies from a database then a secondary encryption tool will not need to be integrated into the system.
