B2C Commerce data model

The first thing to understand about the B2C Commerce data model is simply the structure of the system itself. With Lightning Platform orgs you will have one Production org, which serves as the system-of-record for nearly all code, configuration, and metadata changes. In addition, you’ll have some number of Sandboxes (depending on the Salesforce edition) that are able to synchronize and copy both data and metadata from Production to support development, integration, and testing.

With B2C Commerce, each customer has at least one Realm hosting exactly three primary instances and a larger pool of Sandboxes, each of which contains one-or-more sites.
