Provenance as Dependency Analysisdation for forms of provenance that are intended to show how (part of) the output of a query depends on (parts of) its input. We introduce a semantic characterization of such ., show that this form of provenance is not computable, and provide dynamic and static approximation techniques.

Efficient Inclusion for a Class of XML Types with Interleaving and Countingpe into a set of constraints that completely characterizes the type. We then provide a complete deduction system to verify whether the constraints of one type imply all the constraints of another one.

and the Short Stories of 1910–11s - namely, value indices on tags and text values - are first used, together with structural join algorithms [1, 2, 19]. This approach turns out to be simple and efficient. However, the structural containment relationships native to XML data are not directly captured by value indices.

Datalog Programs over Infinite Databases, Revisitedthm to generate an efficient evaluation scheme of closed queries, which is a generalization of Vieille’s famous QSQR algorithm for top-down evaluation of Datalog programs. A by-product of this work is a rather terse and elegant representation of QSQR.
