Week 11 - Moving from tables to Trees

In this session, I continue the work on tree structures by looking at the difference between table and tree structures as represented in XML format. We will look at some of the motivation behind the use of XML, in particular the problems with complex relational systems, the problem of data interchange and the emerging XML technologies.
