ABSTRACT:
Techniques for replicating modified data to a hierarchical database. A first list comprises records included in a set of records before at least one modification thereto. A second list comprises records included in the set of records after the at least one modification thereto. For each pre-modification record included in the first list and each post-modification record included in the second list having equal identifying values, a target record at the database and having a matching identifying value is modified. Specifically, if both records include corresponding indexes, information about a structure pointed to by the pre-modification record is removed from an index included in the target record, and information about a structure pointed to by the post-modification record is added to the index. If neither record includes an index, the target record is modified to contain at least one changed value included in the post-modification record.
