I´m reproducing a picture that Jean posted in google plus to exemplify multiple inheritance.
I don’t like the mechanism of multiple inheritance (at the conceptual level is sometimes useful but too easy to get it wrong and at the implementation level is just a nightmare since most technologies do not support it so you are forced to find a workaround for it), this examples shows that sometimes is a very elegant solution to express the relationship between a set of concepts. What about you? Do you use multiple inheritance in your models? If so, how do you then deal with it during code-generation?
UPDATE: Via Jean, another great graphical example of multiple inheritance (Jean says that “the drawing below is composed from a Venn Diagram of [email protected]@LeBlancRose_”).
