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 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: 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.

Abstract: Network security is enhanced in a multi-tenant database network environment using a query plan detection module to continually poll the database system to locate and raise an alert for suspect query plans. Security also can be enhanced using a firewall system sitting between the application servers and the client systems that records user and organization information for each client request received, compares this with information included in a response from an application server, and verifies that the response is being sent to the appropriate user. Security also can be enhanced using a client-side firewall system with logic executing on the client system that verifies whether a response from an application server is being sent to the appropriate user system by comparing user and organization id information stored at the client with similar information in the response.

Abstract: Search systems and methods for searching structured data and enhancing the relevancy of search results provided to a requesting user or application. Enhanced search results are provided by searching a cache of a users most recently used items to eliminate or reduce search indexing latency. Also, more relevant search results are provided by re-ranking results based on use history, data security models and/or hierarchical user role models. Further, enhanced search results are provided by including user information in the search index.
