The problem of database repair is a question about relational databases which has been studied in database theory, and which is a particular kind of data cleansing. The problem asks about how we can "repair" an input relational database in order to make it satisfy integrity constraints .
A data control language (DCL) is a syntax similar to a computer programming language used to control access to data stored in a database (authorization). In particular, it is a component of Structured Query Language (SQL). Data Control Language is one of the logical group in SQL Commands.
The cryptographic features are available as functions inside the database as well. SSL / TLS connections are supported in the client–server mode, as well as when using the console application. [citation needed] The database supports protection against SQL injection by enforcing the use of parameterized statements. In H2, this feature is ...

Directory Services Restore Mode (DSRM) is a function on Active Directory Domain Controllers to take the server offline for emergency maintenance, particularly restoring backups of AD objects. It is accessed on Windows Server via the advanced startup menu, similarly to safe mode .
The chkdsk command on Windows XP. CHKDSK can be run from DOS prompt, Windows Explorer, Windows Command Prompt, Windows PowerShell or Recovery Console. [10] On Windows NT operating systems, CHKDSK can also check the disk surface for bad sectors and mark them (in MS-DOS 6.x and Windows 9x, this is a task done by Microsoft ScanDisk).
The dd utility on a Linux boot CD can be used to copy file systems between disk images and disk partitions to effect a bare-metal backup and recovery. These disk images can then be used as input to a new partition of the same type but equal or larger size, or alternatively a variety of virtualization technologies as they often represent a more accessible but less efficient representation of ...
