Nowadays, non-conventional data mainly reside in the Web, adopting the standard formats proposed by the World Wide Web Consortium (W3C), like HTML, XML, RSS, RDF, etc. This entry is focused on those approaches aimed to either integrate non-conventional data with traditional DW/OLAP or to perform ad hoc DW of these data sources.
