A middleware prototype for storing and quering XML documents in RDB using XParent model mapping schema

In this paper we present a middleware for storing and retrieving XML document in relational databases. To store XML documents in relational databases, several mapping prototypes can be used. In this prototype we chose XParent model mapping method and free of cost available technologies MySQL, Php MyAdmin and PHP classes are used the example. The key to middleware prototype is storing and retrieving XML document in a relational database, providing a user interface for XML manipulation, independent of proprietorship and without doing any modification in its basic structure. As the proposed prototype is using XParent so it will be proved to be an efficient solution with respect to query processing specially recursive XML queries and updating. The middleware prototype can also be used as the benchmarking tool for the researchers to compare various schema-oblivious XML mapping strategies after adding them as new collection.
