DRY says that every piece of system knowledge should have one authoritative, unambiguous representation. Every piece of knowledge in the development of something should have a single representation. A system’s knowledge is far broader than just its code. It refers to database schemas, test plans, the build system, even documentation. Dave Thomas
Muchos hemos leido acerce el concepto de DRY, y instintivamente y con los ejemplos planteados llegamos a decir que DRY es evitar repetir codigo, pero va mas alla de eso, en esto debemos incluir, Test, Construccion, Compilacion, Esquemas de bases de datos, etc.
