This component is used to receive SGDB-triggered notifications. These notifications must be implemented by the developer through triggers or stored procedures in the database.

You can notify the system every time a table is changed, or by warning that a particular operation will be performed (such as a backup or closing box).

For more details, you can check out the component documentation page on the Embarcadero wiki on this link
