    Abstract: Statistics mechanisms in multitenant database environments. A master statistics file is maintained in a multitenant database system. The master statistics file has statistics corresponding to multiple tenants within the multitenant database system. Statistics for a selected table within the multitenant database system are generated. The selected table corresponding to a selected tenant of the multitenant database system. The master statistics file is updated based on the generated statistics for the selected table.

    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.

    Abstract: In accordance with embodiments, there are provided mechanisms and methods for synchronizing a server and an on-demand database service. These mechanisms and methods for synchronizing a server and an on-demand database service can enable embodiments to synchronize a larger amount of data. The ability of embodiments to provide such feature can enable more effective synchronization of a user-level sharing entity database with a multi-user on-demand database service.
