What is data encryption in DBMS?

Database encryption is the process of converting data, within a database, in plain text format into a meaningless cipher text by means of a suitable algorithm. Database decryption is converting the meaningless cipher text into the original information using keys generated by the encryption algorithms.

What are the different methods of database security encryption?
