The next outer layer is the audit-event group. This is an auditing context whose scope has a beginning and an ending controlled by the application developer. The developer adds language statements to the application that identify exactly where and when to start an audit event group and where and when to end the audit event group. During that time, all recorded audit events will be associated with that audit event group context. Any one audit event group context can encompass zero or more database transaction contexts, and only one audit event group context can be active at one time within an application.
