A dataset management system uses a façade API to automate access to data stores maintained by data tenants. The system receives a configuration request from a data tenant and determines whether the configuration request corresponds to an existing data tenant. If an existing data tenant is identified, the system updates the façade API associated with the existing data tenant based on the configuration request. When a client request for data associated with the data tenant is received, the façade API formats the direct query to include the updated parameters and executes the direct query to retrieve data from the data stores.
