Abstract: The problem of storing and querying XML data using relational
databases has been considered a lot and many techniques have been developed.
MXML is an extension of XML suitable for representing data that assume different
facets, having different value and structure under different contexts, which are
determined by assigning values to a number of dimensions. In this paper, we
explore techniques for storing MXML documents in relational databases, based on
techniques previously proposed for conventional XML documents. Essential
characteristics of the proposed techniques are the capabilities a) to
reconstruct the original MXML document from its relational representation and b)
to express MXML context-aware queries in SQL.
