Could you not just use a common table with an extra field like "OwnerID"to keep the data separate for each user and query with a
SELECT FROM dbo.CommonTable WHERE OwnerID =
...
What you are really talking about is "Row-level security", which as a way of securing what is called "multi-tenant" databases and applications. Multi-tenancy has some specific requirements including that all tenants have the same schema/design, which is not stated or implied by the OP's post.

Yikes! I'd say so. Upgrades to the data model must be entertaining.

it's not too bad, Grant. The presumption is that all tenants are using the same software and schema, just that every data row is tagged with a Tenant ID and every access has to be filtered based on it. the filtering can easily be made bulletproof through the use of a universal layer of Views, and (owner)Schema security that forces all access to the tables through those views. (Hmm, maybe I should write an article on this ...) :)
Anyway, (design)schema upgrades are only
slightly
more complicated than a single-tenant environment.
