Class path based database operations

Abstract:

The present approach assigns a code to each node class of a data tree modeling a database. The node class codes may be used to generate a node class path for each node class. This class path may be used as a discriminator to reference a given node class or portion of the tree including the class path and may be stored in a field of the database and/or cached. Use of the class path in query operations reduces the complexity of certain queries, thereby speeding up query performance.
