Enabling multi-tenant access to respective isolated data sets organized using different application schemas

Multi-tenant access to respective isolated data sets organized using different application schemas is disclosed. Multiple tenants store respective data sets in separate datastores. The datastores are organized using different application schemas, each derived from a same base schema. However, the tenants share access to a same application. The application receives a first request from a first tenant and a second request from a second tenant. The application serves the first request by accessing a first data set organized using a first application schema. The application serves the second request by accessing a second data set using a second application schema.
