translate each XML query (e.g., expressed in W3C's XQuery) to SQL queries expressed against the shredded documents. ...
In this paper, we propose an alternative approach that builds on relational database technology, but shreds XML documents dynamically. ...
The foundations for dynamic shredding arose from our previous work [8] . ...

We describe ShreX, a freely-available system for shredding, loading and querying XML documents in relational databases. ...
It provides generic (mapping-independent) functions for loading shredded documents into relations and for translating XML queries into SQL. ...

Consequently, an RDBMS can unify the management of both relational data and JSON data in one platform and use SQL with an embedded JSON path language as a single declarative language to query both relational ...
