Abstract: In accordance with embodiments, there are provided mechanisms and methods for pushing an application update between tenants of a multi-tenant on-demand database service. These mechanisms and methods for pushing an application update between tenants of a multi-tenant on-demand database service can enable tenants providing the application update to force instances of the application utilized by other tenants to be updated. This may allow the tenants providing the application update to ensure that instances of the application utilized by other tenants are updated.

Abstract: In accordance with embodiments, there are provided mechanisms and methods for versioning components of an application. These mechanisms and methods for versioning components of an application can ensure that an updated application maintains backwards compatibility, such that the application developer may maintain a single application while supporting multiple prior versions of the application.

Abstract: More efficient querying of a multi-tenant database using dynamic tuning of database indices. A layer of meta-data associates data items with tenants, e.g., via tags, and the meta-data is used to optimize searches by channeling processing resources during a query to only those pieces of data bearing the relevant tenant's unique tag.

Abstract: The present invention provides techniques for storing information on a multi-tenant database system to control query latency that includes a method that stores the information on the database among a plurality of tables arranged in columns and rows. For each of a subset of the plurality of tables, sets of the rows are distributed amongst different storage nodes on the database, with the set of rows stored at a common node having a common index value. Data storage and retrieval capabilities to the database are provided to allow access to the information, in response to requests from one of a plurality of remotely disposed computer systems. The retrieval capability includes a query condition that includes a query index value, with the query condition and the query index value being established to control retrieval latency.

Abstract: The present invention provides techniques for managing process space on a multi-tenant database system that features a method that provides to multiple users of two or more organizations, over a network, access to information stored in a database repository shared by the two or more organizations. The database repository implements security protocols to restrict a set of first users to a first sub-portion of the information. The set of first users belongs to one of the two or more organizations. The first sub-portion of the information is different from a second sub-portion accessible by users from another organization. Access of the information by the multiple users is monitored. A first processing space for the set of first users is generated in response to the access of the database repository. The first processing space is distinct from a second processing space for the users from the other organization.

Abstract: The present invention provides techniques for managing information on a multi-tenant database system. In one embodiment a method comprises storing the information on the database among a plurality of tables. The plurality of tables is arranged in columns and rows. Each of a subset of the plurality of tables has sets of the rows distributed amongst different storage nodes on the database. A first of the sets is located at a first node, and a second of the sets is located a second node. Data storage and retrieval capabilities are provided to the database, including access to the information, in response to requests from one of a plurality of remotely disposed computer systems. Also disclosed is a machine-readable medium carrying one or more sequences of instructions for managing computer applications when executed by one or more processors and cause the one or more processors to carry out steps of the method.

Abstract: Systems and methods for hosting variable schema data such as dynamic tables and columns in a fixed physical database schema. Standard objects, such as tables are provided for use by multiple tenants or organizations in a multi-tenant database system. Each organization may add or define custom fields for inclusion in a standard object. Custom fields for multiple tenants are stored in a single field within the object data structure, and this single field may contain different data types for each tenant. Indexing columns are also provided, wherein a tenant may designate a field for indexing. Data values for designated fields are copied to an index column, and each index column may include multiple data types. Each organization may also define custom objects including custom fields and indexing columns. Custom objects for multiple tenants are stored in a single custom object data structure.

Abstract: The present invention provides techniques for managing a multi-tenant database system. In one embodiment the method includes providing access to data stored in a multi-tenant data structure that is implemented by storing data for multiple tenants on a pool of computer servers defining the multi-tenant data structure that having a plurality of data columns and one or more index columns. The one or more index columns define a first data field for a first tenant of the multi-tenant data structure and a second data field for a second tenant of the multi-tenant data structure. The first field indicates a first data type and the second field indicates a second data type, wherein the second data type is different than the first data type. Once created, records having data values in the first and second fields are stored to a single column in the data structure. The single column includes data values having different data types for different tenants in the multi-tenant data structure.
