The segment membership table is one of the audience level system tables that Campaign creates when you define a new audience. If you use strategic segments in
Campaign flowcharts or Optimize sessions within
Optimize, you must map the segment membership table to a database table that defines segment members.
For example, if you plan to use the default Customer audience in conjunction with strategic segments, you must map the
Customer Segment Membership system table to the
UA_SegMembership segment membership database table. For other audiences used with strategic segments, you would map the system table
<audience name> Segment Membership to the database table that defines the segment members. You can use
UA_SegMembership as a template for the database table.
Using strategic segments in Campaign flowcharts and
Optimize sessions is optional. If you are not using strategic segments, the best practice is that you do not map the segment membership table. Mapping an audience's segment membership system table causes
Campaign or
Optimize to refresh the table each time you run the flowchart or Optimize session that includes the audience. This is unnecessary processing overhead if you are not using strategic segments.
