What is a method?
This post is also available in: English (Engels)
(Americans often refer to a method with the term “methodology”, which is not entirely correct semantically, as it would mean “the science of methods”)
Inspired by the book by Ian Graham et.al.,
I share the following UML model of a method with you. It shows what a (proper) method consists of. To illustrate, UML itself for example is a Modelling Language, consisting of a notation and a metamodel. ER diagrams for example are not much more than a notation (with a rudimentary and inconsistent metamodel).
I like the model, simplistic as it is, because it gives a nice overview of all aspects that are (or should be) present in any framework that wants to call itself a method, including the main relationships. As you notice this UML diagram is more a structural model, and says nothing about responsibilities (which is what you normally would want to see in a UML diagram).
