/* This is an example of a data presentation from a set of
normalised tables via a PHP web page.  Extra example written
during a Well House Consultants training course as demonstration
of principles.

* A number of CLIENTS
* Each client commissions a number of BROCHURES
* Each brochure is available in a number of TRANSLATIONS
* Each translation goes through a number of VERSIONS until it's released

All 4 tables are joined in a select which was tested out with
test data and the mysql client program prior to embedding it into
this test program.

A fifth table contains details of languages; that's included in
the join too.

Same SQL to create the database and tables, populate the tables
with data, and run the test select can be found under
          http://www.wellho.net/resources/S154.html
