Yes, of course you _can_, but it is much easier if the database structure etc is exactly the same for every record you want to work with.

Well, that is how a thick registry works. By having epp as a synchronization protocol. If the registry is to have the information about who is the holder of each domain, while the registrar is to invoice the customer, the registrar definitely also will have information about the same holder. Transfer of domains and contacts, and updates of contact etc information ends up being an "interesting" game where both parties are moving around the pieces on the chess board at the same time.

In this case, we more or less only talk about the ability for the registrar to issue a query like:

- What domains am I sponsor for?

- What contacts am I sponsor for?

Etc.
