Abstract: A method for historically synchronizing tag data related to a computer network is provided. A network management server compares a relations table of entities from a first database to a corresponding relations history table of entities from a second database. The network management server identifies from the comparison a pair of entities having a changed relationship. The network management server updates the relations history table of entities with the changed relationship in the second database. The network management server updates a path and level between a root of a tree of tags and each tag of the pair of tags in a historical configuration details table of tags in the second database based on updating the relations history table of entities.

Abstract: A method for historically synchronizing configuration data of a computer network is provided. A network management server collects from a first database a first plurality of configuration tables corresponding to a plurality of entities in the computer network according to a hierarchy of the entities when an entity in the computer network has changed. The network management server identifies the entity that has changed. The network management server adds a history identifier to an entity configuration table of the first plurality of configuration tables. The entity configuration table corresponds to the entity that has changed. The network management server updates a second plurality of configuration tables in a second database with the first plurality of configuration tables.
