Uncle Bob 11 May 2014 Craftsmanship
Frameworks are powerful tools. We'd be lost without them. But there's a cost to using them.
The relationship between a programmer and a framework is similar to the relationship between an executive and an administrative assistant. The framework takes care of all the necessary details, so that the executive can focus on high level decisions.
Think of Rails, or Spring, or JSF, or Hibernate. Think about what writing a web system would be like without these frameworks to help you. The idea is disheartening. There'd be so many little piddling details to deal with. It'd be like endeavoring to construct a mnemonic memory circuit using stone knives and bearskins.
And so we gleefully use those glittering frameworks. We joyously intermingle our code with the frameworks' in anticipation of all the benefits they promise. We make the mistake that so many executives have made before us. We marry our secretary.
