Expressive power and data complexity of nonrecursive query languages for lists and trees (Extended Abstract)
Summary: With list/tree primitives, nonrecursive Datalog/Prolog/FO all have the same expressive power; their range‑restricted fragments equal relational algebra and every query is a Boolean combination of range‑restricted queries. Data complexity is polynomial (in AC0 under natural encodings): lists/trees add no expressiveness but induce a nonelementary program‑complexity blowup vs. PSPACE for the relational counterparts.
