UPDATING RELATIONAL DATABASES THROUGH XML VIEWS
Vanessa de Paula Braganholo, Carlos Alberto Heuser, César Roberto, Mariano Vittori · 2001
This paper presents an overview of a process for updating relational databases through XML views. The process is based on a query language called R2X and on a concept of normalization for XML views. The R2X language constructs XML views from relational databases, while normalization removes the ambiguity in an XML view, thus solving the update problem. In order to normalize an XML view, we benefit from the relation between XML and non-first normal form relations (NF ).
