Patent number: 9619492Abstract: In one embodiment, a method for data migration includes: receiving intermediate data and corresponding key value-row location information mapping list; importing each row of the intermediate data to a corresponding row of a target data table, where each row of the target data table has a target physical row ID; and establishing, by a computer processor, a target index of the target data table based on the target physical row IDs and the key value-row location information mapping list. With the method or system of this invention, the efficiency of reestablishing a data index after data migration can be improved.Type: GrantFiled: February 27, 2014Date of Patent: April 11, 2017Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Ying Ming Gao, Ang Li, Jian Liu, Zhuo Yin, Xian Zou

Patent number: 9189506Abstract: Managing database indexes includes creating a main index and creating at least one service index that is configured for recording a change to a node to be updated in the main index. Managing database indexes also includes detecting whether an operation that involves the main index and is performed on the database appears in the database, and maintaining the main index using at least one service index in response to the operation that involves the main index and is performed on the database, appearing in the database. The maintaining is performed based on changes to a node to be updated in the main index that are recorded in the at least one service node.Type: GrantFiled: February 13, 2012Date of Patent: November 17, 2015Assignee: International Business Machines CorporationInventors: Ying Ming Gao, Jia Huo, Kai Zhang, Xian Zou

Patent number: 9043275Abstract: The present invention relates to the technical field of data or file synchronization. In particular, the present invention relates to a method and system for data synchronization using character string matching. Provided are a method, computer program product, and system for data synchronization between a source node and target node. An old copy and a new copy of data to be synchronized is received. A block map is generated according to the difference determined using character string matching between the old copy and the new copy. The block map, which includes the position information of unchanged blocks and the position information and contents of changed blocks, is transmitted to a target node.Type: GrantFiled: May 14, 2012Date of Patent: May 26, 2015Assignee: International Business Machines CorporationInventors: Ying M. Gao, Jia Huo, Hong Xiao, Yuan L. Yang, Kai Zhang, Xian Zou
