Abstract
Embodiments of the present invention provide computer-implemented methods, computer systems and computer program products. According to one embodiment of the present invention, an index of a database is obtained, where the index includes at least one node associated with index information of at least one old data entry that has been deleted from the database, and the node is marked as invalid. Then, a node included in the index is selected based on a key value in index information of a new data entry in response to the new data entry being inserted into the database. Next, the selected node is updated with the index information of the new data entry.
