A national workout studio chain is introducing a new Family discount program. They have already deployed AEP with the following data model:
Members Schema (Individual Profile Based):
Primary ID: Member ID
Secondary IDs: Email Hash. Phone Hash
Training Sessions Management (Experience Event):
Primary ID: Member ID
Secondary IDs: ECID
Subscription Management (Experience Event):
Primary ID: Email Hash
Secondary IDs: ECID
The workout studio wants to be able to use all of this information together with the family details to segment For example, they want totarget families where one familymember trams daily or one family member has the yearly subscription plan.
To start collecting Family information, the workout studio creates a form where the members can create a Family account and associate the different members to it The form will collect a list of Member IDs and generate a Family ID. A data architect will design a new schema to store the Family information.
Which identities should be used in the schema(s) to collect this form information?
