Unified Auditing is a new feature in Oracle Database 12c, and it introduces new auditing architecture. Some of the characteristics of unified auditing are:
A single audit trail
Being based on a read-only table
Extensible Audit Framework for additional columns
The separation of audit administration with new roles
Auditing performance is better, especially when used in the queued-write mode
Figure 1 depicts that in preunified auditing architecture, there were many audit trails. Now, there is one consolidated unified audit trail, which simplifies management, and auditors can more easily find audited data they are looking for.

In Figure 2, a new architecture is shown:
