The technique for identifying the person who is attempting to access the DBMS is known as authentication.
A database management system (or DBMS) is essentially a computerised data storage system. Users of the system are given the ability to perform a variety of operations on such a system, such as manipulating the data in the database or managing the database structure itself.
Authentication is a technique to determine whether or not someone or something is who or what they claim to be. Authentication technology controls system access by determining whether a user's credentials match those in a database of authorised users or in a data authentication server.
