About audience levels and system tables

Each audience level you create requires the following associated system tables:

A contact history table

A detailed contact history table

A response history table

A segment membership table

These system table entries are automatically created when you create the audience level. You must then:

Create the physical database tables in the Campaign system table database.

Map these system tables to the database tables.

IBM recommends that you map the segment membership table only if you are using strategic segments with Campaign flowcharts or Optimize sessions in Optimize.
