Second, whenever an object changes its role — perhaps you hire one of your graduating students to become a professor — you need to copy the data into the appropriate table and assign it a new OID.

将弹出一个对话框，可以从中选择与角色关联的业务对象。
A dialog then pops up where the business object associated with the role can be selected.
角色必须与参与该关系中的每个业务对象关联。
A role must be associated with each business object that participates in the relationship.
角色可以表示相应的元数据，即描述业务对象中的哪个属性将与该关系的其他角色中所描述的属性关联。
The role represents metadata that describes which property in the business object will be correlated to the properties described in the others roles that are part of the relationship.
它们将已建立的一系列任务、决策、对数据对象的引用、策略、角色及测试合并起来。
They incorporate established series of tasks and decisions, references to data objects, policies, roles, and measurements.
矩阵为每组交互并交换信息的对象或角色确定截然不同的IER。
The matrix identifies a distinct IER for each pair of objects or roles that interact and exchange information.
角色代表元数据，描述业务对象中的哪个属性与属于该关系的其他角色中描述的属性相关联。
The role represents metadata that describes which property in the business object is correlated to the properties described in the others roles that are part of the relationship.
完成这个角色类之后，我现在可创建角色对象，如清单9所示。
With the character class complete, I can now create character objects, as shown in Listing 9.
然后，就可以将那个角色对象的从属关系授给被归为在一个特定“任务角色”中的任何用户。
Any user who is classified to be working in a particular "job role" can then be granted the membership of that role object.
包支持多次声明一个对象(比如多种角色)，并且可以在序列不重要时使用包。
Bags support multiple declarations for an object, such as multiple roles, and can be used when the sequence is not important.
序列用于定义对象的次序，比如机构中人员角色的层次结构。
Sequences support a defined sequence for an object, such as the hierarchy of a person's role within in an organization.
模式匹配在函数式编程中扮演了中心角色，就好像多态在面向对象编程中扮演着中心角色一样。
Pattern matching plays a central role in functional programming just as polymorphism plays a central role in object-oriented programming.
实现为ejb的业务对象扮演被动对象的角色。
Business objects, implemented as EJBs, are playing the role of passive objects.
