Chapter 1: Introducing multi-tenancy
What is a tenant?
A tenant is a separate and distinct set of users within a multi-tenant database. For
example, a tenant can equate to one company, or a division within one company.
Access to a tenant’s data is restricted to users that are authenticated to the tenant via
a security domain. For information on security domains, see the “Security domains”
section on page 80 for a brief discussion, or see OpenEdge Getting Started: Identity
Management for complete details.
For tables that are defined to be multi-tenant, each tenant has its own instance of the
multi-tenant table (unless a partition for that table has explicitly not been allocated for
that tenant). Tenants have access to the data in the instances designated for that
specific tenant as well as to tables that are shared.
Two special cases of tenant data access are as follows:
• Super-tenant users — Super-tenants users (or simply super tenants) can access
all of the data in the database, typically for maintenance purposes.
• Tenant groups — Groups allow more than one tenant to access the same data
for an instance of a table.
