Asterix

This module is meant for PHP developers using Drupal as a Framework rather than a CMS. Drupal's node system is perfect for content but what if you want to develop a web application in contrast to a website? The node system with CCK and views can be used to build relational database systems but sometimes that's just not the solution you need.
Enter Asterix, a configuration file driven application generator for building relational database web applications, fast! Start with a simple configuration and build upon that. Formerly known as RAD and more recently called AGILE development is made simple with Asterix.
