Proceedings 2001 International Database Engineering and Applications Symposium, 2002
XML data is different from data found in relational databases in several important respects. The article discusses these differences and why they justify development of a new query language for XML. It also reports on the activities of the W3C working group on XML queries.

A graphical query language is a visual language which is intended as a database interface and which employs visual metaphors in order to express the semantics of a database language. The TableTalk graphical query language assumes an objectoriented data model and is based upon the notion of a functional query language.

The Modal Query Language MDatalog
Fundamenta Informaticae, 2001We propose a modal query language called MDatalog. A rule of an MDatalog program is a universally quantified modal Horn clause. This language is interpreted in fixed-domain first-order modal logics over signatures without functions. We give algorithms to construct the least models for MDatalog programs. We show PTIME complexity of computing queries for
