Some XML query processors operate on an internal representation of XML documents and
can leverage neither the XML storage structure nor the possible access methods dedicated …

Based on Canny operator and mathematical morphology, a new cell-based method for

Large data graphs with complex and heterogeneous structure, possibly featuring typed data
and an ontol-ogy encoding the application-domain semantics, are widely used nowadays …

We study the problem of storing XML documents using relational mappings. We propose a
formalization of classes of mapping schemes based on the languages used for defining …

The rapid development of XML technology improves the WWW, since the XML data has
