Abstract
A system and method to receive a query against a plurality of data objects that are sorted, at least conceptually, to follow a hierarchical order and support a preorder traversal arrangement and a postorder traversal arrangement; translate the query into an executable query plan including at least one instance of a hierarchy rearrange operator, the hierarchy rearrange operator to rearrange an input including one or more of the plurality of data objects from one of a preorder traversal arrangement and a postorder traversal arrangement to a corresponding opposite thereof; execute the executable query plan including the at least one instance of the hierarchy rearrange operator; and generate a query result based, at least in part, on the input of the one or more plurality of data objects being rearranged in the respective preorder traversal arrangement and a postorder traversal arrangement.
