The ATK Application Framework (PHP)

Achievo ATK is an object oriented Web Application Framework, written in PHP.

It is targeted at developers who wish to focus on business logic, instead of coding HTML.
Where other application frameworks mainly provide a large set of utility classes, ATK provides a complete framework that requires only small amounts of code to get usable applications, while maintaining full flexibility.

In other words, even 10 lines of code get you a working application, but everything generated for you, can be 100% customized.

It is our belief that Achievo ATK will revolutionize the way business applications are built. We therefor refer to ATK as a 'business framework' or 'enterprise framework', if you will.

ATK is sometimes compared to 'Ruby on Rails'. ATK is very different though, but it is based on the same 'Don't Repeat Yourself' principle, and it has some functionality in common.
