User interface support for large hierarchies

Abstract:

A visual depiction of a hierarchy stored at a server computer can be presented at a client computer that interacts with the server computer as operations are performed on the hierarchy. Efficient execution of operations and determination of which nodes are visible within the hierarchy can be supported without sending the entire hierarchy back and forth between the client and the server. Drill state in the user interface can be preserved during operations. The server can support multiple clients interacting with the hierarchy at the same time.
