Igenerate views for each tenant and they can access their own data in the underlying table through these views. Now if
forgetto address the right tenant in my client code(it still happens sometimes) and try to directly access the base
tablesI get a strongly worded reminder from the server.
1. If you have 50 tables and say 100 tenants, we are talking about 5,000 views. I am not sure
whether it is any more elegant than having 100 schemas.
2. In your approach you can do any phased DDL upgrade. It is typical to do rolling upgrades
in a multi tenant databases, starting with least risky tenant.
