In Detail 
Many web applications are implemented in a way that makes developing  them difficult and repetitive. Catalyst is an open source Perl-based  Model-View-Controller framework that aims to solve this problem by  reorganizing your web application to design and implement it in a  natural, maintainable, and testable manner, making web development fun,  fast, and rewarding. 
This book teaches you how to use Catalyst to weave the various  components involved in a web application, using methods and tools you  personally prefer along with recommendations and details on the most  popularly used objects like the DBIX ORM, TT2 Template, and Moose. 
This book will take you from how the MVC pattern simplifies creating  quality applications to how Catalyst allows you to tap this power  instantly. It explains advanced design patterns and concludes with the  improvements that Moose brings to all this. It also incorporates  valuable suggestions and feedback received from the community members  and our customers. By the end of the book, you will be able to build  clean, scalable, and extendable web applications. This book embodies  Catalyst's philosophies of Do It Yourself and Don't Repeat Yourself.
