Abstract
A method and apparatus for “drilling down” through a tree-based hierarchy are provided. Node descriptors corresponding to the nodes in the tree-based hierarchy are contained in entries in a data structure. Each node has a descriptor included in a first field in at least one entry in the data structure. A second field of the corresponding entry contains a node descriptor of a descendant node of the node corresponding to the descriptor in the first field. In response to user input, a descendant tree for a selected node is displayed by recursively searching in the first field of each entry in the data structure. Similarly, an ascendant tree is displayed by recursively searching in the second field of each entry in the data structure.
