A DataBase built using XML. Small XMLDataBases might be contained within a single file or as big as the portion of the WorldWideWeb that's coded in XHTML.
XSLT is to an XMLDataBase what SQL is to a RelationalDataBase.
In many ways the move to unstructured and semi-structured XML databases is based on a reaction to high level of rigidity in PostRelationalDataBases and a return some of the aspects of NetworkDataBase?s. In theory XML Schemas can be used to impose and reason about the structure of XMLDataBases, but experiance tells use that most users are unwilling to check for well-formedness, let alone validity.
