TL;DR: This article investigates the axiomatizability and implication problem for XML keys with nonempty sets of simple key paths, and proposes a set of inference rules that is indeed sound and complete for the implication of such XML keys.

Sven Hartmann,Sebastian Link +1 more
TL;DR: Not NULL constraints are established as an effective mechanism to balance not only the certainty in database relations but also the expressiveness with the efficiency of entailment relations.

Designing information-preserving mapping schemes for XML
TL;DR: An instance of this framework, the LILO algorithm, is studied, and it is shown that it provides significant performance improvements over Edge++ and introduces constraints that are efficiently enforced in practice.
