Patent number: 8156085Abstract: A cache server is provided in a network for storing Java objects for retrieval by one or multiple application servers. Application server(s) are configured to request an object from the cache server, rather than requesting the Java object directly from a database, so as to reduce processing load on the database and free up database resources. Responsive to a request for a Java object from an application server, e.g., in an HTTP request, the cache server determines if the object is stored in memory and if so, serializes the requested object and sends the serialized object to the requesting server, e.g., in an HTTP response. The requesting server then deserializes the Java object. If the object is not stored in memory, the cache server instantiates the object (typically by requesting the object from the database), serializes the instantiated object and sends it to the requesting server. Cache coherency methods are also provided.Type: GrantFiled: March 30, 2007Date of Patent: April 10, 2012Assignee: salesforce.com, inc.Inventors: Frank Dominguez, Jr., Dave Moellenhoff, Eric Chan

Patent number: 8131713Abstract: 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.Type: GrantFiled: April 14, 2010Date of Patent: March 6, 2012Assignee: salesforce.com, inc.Inventors: Craig Weissman, Dave Moellenhoff, Simon Wong, Paul Nakada

Publication number: 20120047570Abstract: 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.Type: ApplicationFiled: November 1, 2011Publication date: February 23, 2012Applicant: salesforce.com, Inc.Inventors: Eric Chan, Craig Weissman, Paul Nakada, Dave Moellenhoff, Todd McKinnon

Publication number: 20100274779Abstract: 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.Type: ApplicationFiled: April 15, 2010Publication date: October 28, 2010Applicant: salesforce.com, Inc.Inventors: Craig Weissman, Dave Moellenhoff, Simon Wong, Paul Nakada

Publication number: 20100235837Abstract: 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.Type: ApplicationFiled: April 16, 2010Publication date: September 16, 2010Applicant: salesforce.com, Inc.Inventors: Craig Weissman, Dave Moellenhoff, Simon Wong, Paul Nakada

Publication number: 20100191719Abstract: 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.Type: ApplicationFiled: March 31, 2010Publication date: July 29, 2010Applicant: salesforce.com, Inc.Inventors: Craig Weissman, Dave Moellenhoff, Simon Wong, Paul Nakada
