Abstract
Some embodiments of the present invention include a method for merging nodes in hierarchies and include receiving, by a database system, a request to merge a first node in a first hierarchy of a plurality of nodes into a second node, the first node in the first hierarchy having child nodes; determining, by the database system, whether the merge request violates each of a plurality of constraints, the plurality of constraints comprising circular dependency of nodes, deleted node and ordering of nodes; and re-parenting, by the database system, in response to a determination that the merge request does not violate each of the plurality of constraints, the child nodes of the first node in the first hierarchy of nodes to the second node in response to the merging of the first node into the second node.
