Advanced Higher: Creating a Database Driven Website using HTML, SQL and PHP

This resource takes pupils through the process of creating a Database Driven Website using XAMPP to create their server and MYPHP Admin for PHP and SQL. The Web Application I use is Microsoft Expression 4, but it can be done on any other Web Authoring Software. This booklet has made the Unit Assessment so much more manageable for my AH Computing Science pupils.
