Patterns

Without sounding trite, as this topic is all over the software world currently, patterns can save you a lot of time. For years, I've tried to understand them, learn how to use them and just in general up my skills. This is proved difficult though, as the materials are very difficult to understand. Then, just a few weeks back I was at he Data and Object Factory site when I saw their new product the Design Pattern Framework. Now this is what I had been looking for.

Instead of theory and essays on the patterns, this is the PDF guide, Vision diagrams, and complete code samples illustrating how the patterns work! Including, much to my liking, a demo ecommerce asp.net web application utilizing the patterns. I've learned a ton in just a few days of using the product and begining to understand simple things like a singleton, an abstract factory or the strategy pattern.
Extremely clean code is what you get, and the confidence in what I do DOES help.
