Hi Robert,
it is fairly standard PHP website, with MySQL 4.1.x and PHP 4.x on a low cost Linux-based host. Servoy handles all editoral aspects of the site and the order processing.
There is a much more sophisicated PostgreSQL database in house. When records are edited in Servoy, I use the record copying facilities in the database manager to push data to MySQL website database. We also have a button on the order screen for fetching new orders from mySQL. The staff get emails created by PHP when new orders arrive, so the know when to fetch new orders.
In the long run I expect to change web host and move everything to PostgreSQL. MySQL falls over if you send it a complex or buggy query. PostgreSQL is much more robust and is supposed to be much faster than mySQL when the indexes no longer fit into RAM.
See
www.wildy.co.uk, everything you see is edited from Servoy, including the menu structure ;-)
