看懂背後的決策。
01
All tables include a tenant_id FK to Tenant to enforce data isolation at the application level.
02
Users, contacts, leads, deals, and activities are scoped per tenant.
03
Relationships are defined with mandatory foreign keys and many-to-one cardinalities.
Use this pattern when building a multi-tenant SaaS application where simplicity and resource efficiency outweigh strict physical data isolation, and row-level security is managed in the application layer.
