Patent number: 10152577Abstract: Cross tenant data access is provided by creating a logic view in a meta database with respect to at least a first tenant of a group of tenants and according to metadata about the respective tenants. The logic view is based upon first data owned by the first tenant as well as second data that is owned and authorized by at least another tenant of the group of tenants for the first tenant to access. The logic view in the meta database is accessed in response to a cross tenant data access request from an application of the first tenant.Type: GrantFiled: February 24, 2015Date of Patent: December 11, 2018Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Lei Li, Ning Wang, Qi Rong Wang, Xiao Feng Wang, Lei Zhi, Ying Hua Zhou

Patent number: 9483503Abstract: A method and system for placing database. The method includes: receiving a request of creating a new database; determining whether there is a need to migrate current database among current virtual machines based on resource demand and free resource in the current virtual machines; determining database placement plan based on the resource demand, migration strategy and migration cost associated with the migration strategy in response to whether there is a need to migrate the database; and executing the database placement plan. The invention can help a database service provider to optimize database layout in database provision through database migration.Type: GrantFiled: May 24, 2013Date of Patent: November 1, 2016Assignee: International Business Machines CorporationInventors: Jie Qiu, Berthold Reinwald, Qi Rong Wang, Tao Yu, Lei Zhi

Patent number: 9372883Abstract: Embodiments relate to manipulating a multi-tenant database, wherein the multi-tenant database comprises one or more source databases for storing tenant data. An aspect includes receiving a database operation request for one or more tenant-specific logic views, wherein the tenant-specific logic views are created for respective tenants based on mapping information pointing to the one or more source databases included in the multi-tenant database and multi-tenant metadata. Another aspect includes acquiring the mapping information related to the database operation request and pointing to the one or more source databases included in the multi-tenant database. Yet another aspect includes performing a database operation corresponding to the database operation requested for the one or more source databases based on the acquired mapping information.Type: GrantFiled: July 30, 2013Date of Patent: June 21, 2016Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Wen Hao An, Bo Gao, Chang Jie Guo, Ning Wang, Qi Rong Wang, Xiao Feng Wang, Zhi Hu Wang, Lei Zhi
