The Inquiry and Donation models should be extended with a relationship to a Tracking entity.
The Tracking entity for donations should have the following fields:
- impCount
- bImpCount
The Tracking entity for memberships should have the following fields:
- confirmationPageCampaign
- confirmationPage
Maybe the wikiLogin field could also be migrated there (in a backwards-compatible way).
At the moment all these values are lumped in the data field of Membership and Donation.
See https://github.com/wmde/FundraisingStore/issues/36 for ideas on backwards- and forwards-compatibility.
This is a cross-cutting concern for the use-cases T123044, T123043 and T123040.
