Define the tenant
A tenant might be a company, facility, legal entity, or operating unit. The definition affects identity, data isolation, billing, support, reporting, and migration.
Choose isolation from risk
Shared tables, schemas, and databases create different operational costs and blast radii. Select the boundary against verified privacy, scale, support, and recovery requirements.
Design lifecycle operations
Provisioning, export, deletion, backup, migration, and tenant-specific incidents are first-class workflows. If they are not designed, the data model is incomplete.
