Tenant Sub Tenant Hierarchy and Tenant Aware Applications

In Multi-tenant SaaS applications, the word tenant is often assumed to mean a customer organization.But it need not be the only use case. For a BPO's internal application, used by different verticals, each tenant can be one vertical, for which the application is configured differently. For a BFSI (Banking / Finance / Securities / Investment) organization offering a market facing application, the tenant could mean one of the various channels (internal and external) that sell their products. For an ISV with a global network of distributors and resellers, providing solutions to "Retail chains" the tenant could mean any and all of the following: A National Distributor, A Reseller, A Retail chain owner (Corporate office) and a particular retail store.
