We should reasonable balance data sharing and data isolation when we design a multi-tenant database based on SaaS. The tenants' data storage¡¢corresponding to the sub user and the tenants¡¢rights management and data scalability are inevitable problems which should be resolved when we aim to balance sharing and isolation.
