Managing XML documents is problematic when document collections grow. How do we successfully store and query document collections? One solution is a database. In the first part of this tutorial, we will discuss the problem of integrating XML with databases and examine choices, such as relational databases, object databases, object-relational databases and native XML servers. In the second part of this tutorial, we will discuss some of the issues in managing XML with Objects and present a generic architecture for storing XML in a relational database using detailed code examples in Java and Python.

Attendee background

Attendees should have a good understanding of Objects, XML and Databases. Some previous experience using these technologies would also be helpful. The intended audience is professionals charged with the task of evaluating technologies.


This tutorial will be lecture based.
