Event dependencies

As part of the configuration of the conditions for an event, you can require the presence of another event or event value, which creates an event dependency.

There are two available methods for creating dependencies between events:

• Implicit dependency - Discover events can be triggered at the start of session, first page, end of page, on the last page or at the end of the session. These discrete points of evaluation can be used to create implied dependencies. For example, you can guarantee that any event configured to trigger on the last page can reference the output generated by any event triggered at the start of the session.
• Explicit dependency - As one of the conditions of the event, you can specify that another event or event value must be present. Explicit dependencies are only valid between events that share the same trigger point. For example, an event configured to be triggered at Every Hit cannot reference events triggered at Last Hit.

Explicit dependencies can be reviewed through the Discover Event Manager. See "Manage Events - Events Tab" in the Unica Discover Event Manager Manual.
