advancedDatabase Design — Normalization, Denormalization & Multi-Tenant
What is the difference between the three multi-tenant database patterns?
Separate Database: one database per tenant. Maximum isolation, easy backup per tenant. Cons: very expensive, hard to manage at 1000 tenants, sharing schema changes across tenants is complex.

Shared Schema: one database, one schema
