A system serving several restaurants must never let one owner see another restaurant's guests, orders or settings.
Scope every query to the correct business
It is not enough to hide another outlet's data in the interface. Data access should be restricted in application authorization and at the persistence layer. Audit all queries, downloads and background jobs for tenant identity.
Separate roles within each business
An owner, counter operator and waiter need different permissions. Invitations and staff reassignment should not accidentally attach someone to the wrong restaurant or grant broad access.
Test hostile and mistaken access
Try changing record identifiers and switching between two authorized test businesses. Verify that exports, notifications and analytics never mix restaurant data. KyaLoge's development tests require strict tenant isolation before production activation.
Here's what this looks like in practice.
Illustrative situation, not a claim about a real KyaLoge customer.
An owner who manages two restaurants switches accounts. A cached analytics card still shows records from another outlet, even though the page header changed.
A better way to handle it
Restaurant tenancy must be enforced in every query, export, job and API authorization. The front-end selection is not a security boundary. Give staff only the role and outlet access they need.
Use two separate test tenants, attempt cross-tenant identifiers, exports and notifications, and verify rejection at the backend.
Calling a dropdown 'tenant isolation' without verifying database and API access.
What to check before making a decision
- 01Test two unrelated sample restaurants.
- 02Check deep links and API identifiers.
- 03Review export and messaging tenant filters.
- 04Record role revocations and audit events.
Keep the useful part.
Never substitute a visually separated dashboard for actual isolation and authorization testing.
