+<p>Database data can be encrypted by a key that is generated by the DBMS.
+Access to this key is protected by encryption and decryption keys that are

+<p>It is not possible to turn a secure database into a plain-text database

+<p>It is important to note that encrypting a database has an impact on performance.</p>
