XML-Enabled DBMS:
Database system in
which XML data may be stored and queried from
relational tables. Such a DBMS must either map
XML data into relations and translate queries into
SQL, or implement a middleware layer allowing
native XML storing and querying.
XML-Native DBMS (NXD):
Database sys-
tem in which XML data are natively stored and
queried as XML documents. An NXD provides
XML schema storage and implements an XML
query engine (typically supporting XPath and
XQuery). eXist (Meier, 2002) and X-Hive (X-Hive
Corporation, 2007) are examples of NXDs.
XML Data Warehouse:
XML database that
is specifically modeled (i.e., multidimensionally,
with a star-like schema) to support XML decision-
support and analytic queries.
XML Document Warehouse:
An XML docu-
ment repository dedicated to e-business and Web
data analysis.

Database Management System (DBMS):
Software set that handles structuring, storage,
maintenance, update and querying of data stored
in a database.
