  • Data migration
    Patent number: 9619492
    Abstract: 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.

  • Database index management
    Patent number: 9189506
    Abstract: 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.
