Described herein is a means for developing uniquely keyed data when the data involved has no apparent unique key. This situation occurs with hierarchical data in which the node involved is computed by a program. Since relational access using structured query languages does not have a concept of 'HERE', the concept of a unique key has to be developed when hierarchical data is involved.
