After having used these fflib libraries ( https://github.com/financialforcedev/df12-apex-enterprise-patterns ) in a few projects, I have to take a moment to recommend them. If you are doing salesforce development (hear apex custom coding), get these libraries and utilize them, use the naming conventions, and you will have better results. Code will be more organized, readable, and bugs easier to find.
