Multiple Audit Applications can be defined. Each audit application might handle the same raw audit data differently. For example, you might have some raw data that consists of a Node Ref, node properties, and an action. You might then have two Audit Applications, a LoginAuditApplication and a SiteAuditApplication. Audit Applications have recorded values as their output. So given the same initial event, the LoginAuditApplication would produce username and action as recorded values, whereas the SiteAuditApplication would produce site name and action as recorded values. So, the same raw data can be processed in different ways by different Audit Applications. An overview of this is provided in the following diagram:
