One solution would be an integrated query model that would at the same time allow the query of a relational database and of XML data. ...
After having made a detailed study, in this paper we make comparing different systems that link both, databases and XML. Besides, we propose a new system to overcome the limitations found in them. ...
A New Database Query System Based on XML The main aim is to create a system that allows querying relational database and XML documents using the same query system in an efficient way. ...

XML-QL is a declarative, "relational complete" query language and is simple enough that it can be optimized. XML-QL can extract data from existing XML documents and construct new XML documents. ...
We present a query language for XML, called XML-QL, which we argue is suitable for performing the above tasks. ...
Specifically, we take a database view, as opposed to document view, of XML. We consider an XML document to be a database and a DTD to be a database schema. ...

The approach can be generalized naturally to support the temporal management of arbitrary XML documents and queries on their version history. ...
The increasing popularity of XML and XQuery offers a unique opportunity to change this situation, inasmuch as these support temporal information much better than relational tables and SQL. ...
For instance, XPERANTO can build a default view on the whole relational database, and new XML views and queries upon XML views can then be defined using XQuery. ...
