Introduction
XML stands for Extensible Markup Language.
It is designed to describe data and focus on
what data is.
It is used to structure store and to send
information.
It is easy to understand and is self describing.

Data Manipulation Languages
In order for a database to be useful, it should be possible
to store and retrieve information from it. This is the role
of the data manipulation language.

Change of Focus
Until now, we have focussed
on high-level issues, such as
database design and highlevel query languages.
The next few weeks, we will
