第4题：
对于场景：一个公司负责多个项目，每个项目（Project）由一个员工（Employee）团队（ Team）来开发。下列UML概念图中，（41）最适合描述这一场景。
A.图A
B.图B
C.图C
D.图D
正确答案：B
本题主要考查类图和多重度的知识。在UML中，关联的多重度是指一个类的实例能够与另一个类的多少个实例相关联。它又称为重复度。多重度表示为一个整数范围n..m，整数n定义所连接的最少对象的数目，而m则为最多对象数（当不知道确切的最大数时，最大数用*号表示）。最常见的多重性有0..1、0..*、1和1..*。在本题中，根据题目的描述，我们不难看出有4个类，而且由描述“一个公司负责多个项目”可知，公司和项目两个类之间的关联是一种一对多的关联，即项目端是多端，这样就可以排除答案C，另外公司和项目之间并不是一种继承的关系，这样就可以排除答案D。而在A和B选项间，他们的区别就在于A的关联牵涉到了3个类，但其实这种表达方式是不存在的，而B选项中很好地表明了题目的意思，即一个项目由一个团队来开发，而团队中的成员个数至少是一个，或者是多个。 -
