Webtrends Analytics 9 Adminstration Guide, November 2012
An event represents any action on the part of the visitor, such as clicking through an ad, submitting an on-site search, or placing an order.
Events take place at a precise moment in time. Webtrends Visitor Data Mart provides two kinds of events:
Visitor Data Mart out-of-box built-in events. You can modify the attributes of a preconfigured event such as adding, removing, or extending functionality.
You can create a custom event to focus on a visitor action not captured by preconfigured events. Use lookup tables to translate or augment event data.
