Structural Overview

An event is a condition that is detected in the session data stream that triggers an action. See Events.

• A hit attribute is a specified start tag and end tag in session data that can be referenced as a condition for one or more events. Hit Attributes can also be explicit text strings in the data.
  Note: Hit Attributes are not directly applicable to reporting. Hit Attributes are defined in the Discover Event Manager. See "Manage Events Hit Attributes Tab" in the Discover Event Manager Manual.

An event is associated with one or more report groups, which are collections of dimensions on which you can report simultaneously. See Report Groups.

• A dimension is a list of values associated with an event. This list of values can be fixed or can be generated from the session data stream every hour. See Dimensions.
• A fact is the data entity that combines an event and a report group. Facts are the essential storage mechanism for reporting data. See Facts.
  • Some facts can have fact values, which are event instance data that can be configured in the event definition. See Fact Values.
• A label is a grouping mechanism for event and dimension objects. You can organize a set of related objects under a single label. Labels have no impact on data processing.
