This paper defines and demonstrates four philosophies for processing queries on tree structures; shows that the data semantics of queries shuld be described by designating sets of nodes from which v values for attnbutes may be returned to the data consumer; shows that the data semantics of database processing can be specified totally independent of any madhine, file structure, or implementation; shows that set theory is a natural and effective vehicle for analyzing the semantics of queries on tree structures; and finally, shows that Bolts is an adequate formalism for conveying the semantics of tree structure processing.
