Abstract
Methods and systems are provided for querying a database. One exemplary method for obtaining data from an on-demand database supporting one or more tenants involves obtaining model database statistics based on expected utilization information for a tenant and providing the model database statistics to the on-demand database. The on-demand database utilizes the model database statistics to generate a query plan and executes the query plan to obtain data from the model database statistics.
