In one embodiment, a computer system receives an indication that a portion of data at a first node in a first database table is to be modified according to a received update command. The computer system assigns the first database table a base height value indicating that the first database table is the base node in a search for related nodes, accesses one or more other database tables in the database, and identifies at least one other accessed database table that has a node with data related to the modified data of the first node. The computer system assigns the other accessed database table a height value different than that assigned to the base node, orders the first database table and any other identified database tables by assigned height value, and updates the data at each node based on the established height value ordering and the type of update command received.
