Data reads and related data reading processes are described. An example data read method includes: receiving a data read request, the data read request being aimed at target node data stored in a target node of a B+ tree; acquiring node location information, the node location information indicating a storage location of node data in a node data set of the B+ tree, and the node data set including the target node data; and determining a target storage location of the target node data. Beneficially, data stored in the B+ tree can be read and updated efficiently while reducing computing overhead.

Storage management is enabled. An example method comprises: receiving an update request for a target object stored in a first storage block to write the updated target object into a second storage block different from the first storage block; determining a candidate object associated with the target object using a search tree, the search tree indicating a hierarchical relation among a plurality of objects, wherein a first node corresponding to the target object and a second node corresponding to the candidate object share a same index node in the search tree; determining whether the candidate object was updated during a past predetermined time period; and in response to the candidate object not being updated during the past predetermined time period, moving the candidate object from a third storage block into a fourth storage block different from the third storage block.
