Description
Data with a hierarchical relationships where each node can have multiple parents and multiple children comes up, for example, in build of materials applications. This sample application shows how one may handle such hierarchies in memory. Also shows the application of hash tables for quick lookup and provides suitable classes. The architecture is build mostly using interfaces instead of object references.
The sample application was written in response to a newsgroup message. See URL link for the start of the thread.
