HYPERSET/WEB-LIKE DATABASES AND THE EXPERIMENTAL IMPLEMENTATION OF THE QUERY LANGUAGE DELTA - Current State of Affairs
Richard Molyneux, Vladimir Yu. Sazonov · 2007
The hyperset approach to WEB-like or semistructured databases is outlined. WDB is presented either (i) as a finite edge-labelled graph or, equivalently, (ii) as system of (hyper)set equations or (iii) in a special XML-WDB format convenient both for distributed WDB and for including arbitrary XML elements in this framework. The current state of affairs on experimental implementation of a query language ∆ (Delta) to such databases—the main result of this paper—is described, with consideration of further implementation work to be done.
