概念建模-我的绘图正确吗?
我明天要参加一次考试，我们已经获得了一个样题，但是由于该样题没有答案，所以我想在这里问.
I have a exam tomorrow and we have gotten a sample exam, but since there are no answers to this sample exam, Id thought Id ask here.
所以我们开始，这是我不确定ive是否正确完成的问题之一:问:绘制一个描述以下领域的概念模型. 在域中有猴子和香蕉.一只猴子可以吃香蕉，但两只猴子不能吃相同的香蕉.
So here we go, this is one of the questions Im not sure if ive done correctly: Q: Draw a conceptual model describing the following domain. In the domain there are monkeys and bananas. A Monkey can eat bananas BUT two monkeys can not eat the same banana.
A(我认为是正确的): http://gyazo.com/722ee8618bfee76ed9f616d45d800819
A(which I think is correct): http://gyazo.com/722ee8618bfee76ed9f616d45d800819
现在，我认为我的答案不正确的原因是，因为两只猴子能够吃同一根香蕉(或者正确完成了吗?)
Now, the reason why I think my answer is incorrect is because two monkey is able to eat the same bananas (or is it correctly done?)
感谢任何帮助，谢谢...
Appreaciate any kind of help, thanks...
您的模型缺少关联末端，这非常重要.它们在两个方向上都赋予了语义和多重性.一个实现模型将是:
Your model is missing association ends, which are very important. They confer semantics and multiplicities in both directions. An implementation model would be:
|Monkey|--eatingMonkey[0..1]---------eatenBanana[0..*]--|Banana|
这可以防止香蕉被多只猴子食用.这是pidgin UML，所以希望您了解如何制作这样的UML图.
That prevents the banana from being eaten by more than one Monkey. This is pidgin UML, so I hope you understand how to make a UML diagram like that.
由于这应该是概念模型，因此可以将eatingMonkey重命名为is eaten by，将eatenBanana重命名为eats，如下所示:
Since this should be a conceptual model, you can rename eatingMonkey to is eaten by and eatenBanana to eats, as follows:
|Monkey|--is eaten by[0..1]---------eats[0..*]--|Banana|
该模型形成自然语言句子:
That model forms the natural language sentences:
- 猴子吃了许多香蕉.
- 香蕉最多可被一只猴子吃掉.
