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 . 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.

https://doi.org/10.1007/978-1-349-05274-5ues investigated include abstract definitions of computability of stream queries; the connection between abstract computability, continuity, monotonicity, and non-blocking operators; and bounded memory computability of stream queries using abstract state machines (ASMs).

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.
