To 'Create a segmentation' go to 'Manage Segmentations' ( Catalog> Profiles > Manage Segmentations)
There is a difference between 'Creating a segmentation' and 'Adding a contact to a segment':
By 'Creating a segmentation', you will create the structure to collect the information.
By 'Adding a contact to a segment', you will determine that a profile belongs to a segment.
Segmentations are no longer created through the 'Manage DB structure' app. They now have their own app.
Creating a segmentation
Click on 'Create a segmentation' to set-up a new segmentation in any database.
Adding a profile to a segment
After the creation of your segmentation, there are several options to specify that a profile belongs to a segment:
Updating a segmentation
By selecting a segmentation and clicking on 'Update', you will be able to edit several characteristics of an existing segmentation.
You can update:
The name of the segmentation and of its segments
Whether it is mandatory
The default segment
It is not possible to change the database linked to a segmentation, or to activate the segmentation 'History' if it was created without.
Viewing the details of a segmentation
By selecting a segmentation and clicking on 'View', you will get its details, namely:
the characteristics of the segmentations (if it's mandatory, historicized, has a default segment,...)
the number of profiles from your DB who belong to the segmentation, and the breakdown for each segment of an exclusive segmentation
the rules that feed each segment. As said above, automated rules are created in a different app. However, the 'View' button gives you an overview of your rules directly in the 'Manage segmentations' app. This allow you to easily find how your profiles are assigned to each segment.
