	Make the audit trail component independent

	Moves audit trail implementation away from applications
		Not compromising security to the application developers and
		reduces complexity of applications ( Transparency for the app developer )
	Audit based on application transactions ( “actions” ) rather than database operations
	Provides consistency of Audit Trail for the entire system in terms of
		Audit Trail Format
		Access to Audit Trail
		Audit Trail Policy Format
	Database components need not be concerned about Audit Trailing resulting ease of design of data schemas
