摘要： Mechanisms and methods for pushing data to a plurality of devices of a plurality of organizations are provided. Queries are handled in bulk for a group of users of an organization or the entire organization, and limited results are sent to a middle tier server between the database system and the user devices. These mechanisms and methods for pushing data to a plurality of devices enable an efficient and transparent transfer of data to user devices. This efficient and transparent transfer of data can enable mobile devices of many organizations to seamlessly have the data that is required to perform business.

摘要： Methods and systems for query optimization for a multi-tenant database system are provided. Some embodiments comprise receiving at a network interface of a server in a multi-tenant database system an original query transmitted to the multi-tenant database system by a user associated with a tenant, wherein the original query is associated with data accessible by the tenant, and wherein the multi-tenant database system includes at least a first index and a second index. Metadata associated with the data is retrieved, wherein at least a portion of the data is stored in a common table within the multi-tenant database system. A tenant-selective query syntax is determined by analyzing at least one of metadata generated from information about the tenant or metadata generated from the data accessible by the tenant. An improved query is then generated using the query syntax, wherein the improved query is based at least in part upon the original query and a result of a join between a first number of rows associated with the first index and a second number of rows associated with the second index.
