Answer:

The definition for the problem is listed in the section below on the explanations.

Explanation:

For SQL Server

  • Data Recovery: Data recovery is done well on SQL Server. It is achieved by the restoration method. Behind this, a sysadmin must reconstruct a collection of SQL backups throughout a restore series that is technically right as well as relevant.
  • Data Security: There are several approvals as well as limits for accessing main data objects or databases. These data are accessed only by the approved clients.
  • Concurrency Control: This is essentially synchronization of the evidence or information accessed by multiple users as well as from separate locations.

Concurrency or Competitiveness control becomes accomplished with SQL Server Portable, using locking to further improve security. The locking regulates how multiple individuals can simultaneously navigate & alter shared storage, without interfering with one another.
