Data that is created within an application session. At the end of the session, it is discarded or reset back to its default and not stored in a database.

Once the data in a record has been updated or changed its previous versions becomes a unnecessary one it may occupy space too so its better to eliminate the previous version of records.

Transient data is applet data, which is cleared either when the applet or deselected or when the card is reset. Transient data is stored in a dedicated RAM area and is typically used to store session data (like Secure Messaging session keys). The transient API is defined in javacard.framework.JCSystem.

There is always a change when we update the existing records. This will neglect the old records and replace them.
