Modelos são modelos. E isso é maravilhoso.

Dizem que quando a gente coloca a referência, daí não é plágio nem pirataria. Que bom, pois assim posso colocar a foto e o excelente parágrafo que Eric Evans apresenta em seu livro sobre Domain Driven Design:

The 18 century Chinese map above represents the whole world. In the center and taking up most of the space is China, surrounded by perfunctory representations of other countries. This was a model of the world appropriate to that society, which had intentionally turned inward. The worldview that the map represents must not have been helpful in dealing with foreigners. Certainly it would not serve modern China at all. Maps are models, and every model represents some aspect of reality or of an idea that is of interest its. It is a simplification. It is an interpretation of reality that abstracts the aspects relevant to solving the problem at hand and ignores extraneous detail.

Bom, acho que o texto diz tudo.

Ah, e meninos, estudem!
