mashup解决方案的不同之处在于用户角色和用于创建独特价值的聚合的数据集。
The differences in the mashup solutions are the roles of the users and the data sets being aggregated to create unique value.
一个角色可以代表多个用户，但它也代表一个用户集可以执行的权限。
A role can represent multiple users, but it also represents the permissions that a set of users can perform.
默认角色和默认策略共同构成默认授权：多维数据集上针对没有显式访问规则的用户的隐式访问规则。
Together, the default role and default policy make up the default authorization: the implicit rule of access on the cube for users with no explicit rule of access.
这种变更可以破坏应用程序对一些用户的易访问性，根据项目的角色集分析每个变更。
Such changes can destroy an application's accessibility for some users; every change should be analyzed with regard to the project's set of personas.
该解决方案应该基于用户的角色，为经过身份验证的用户提供对所供应的服务集的访问。
The solution should provide an authenticated user with access to a provisioned set of services based on the user's role.
最后一节的主要目标是提供功能性分类的详细信息，帮助您根据用户的角色和功能对整个用户集进行分类。
The key objective of this last section is to obtain the details for a functional segmentation that lets us sort the entire set of users according to their role and function.
接下来，我们将定义安全角色。安全角色是具有安全资源(如servlet、JSP、EJB或SCA组件)及方法的访问权限的命名用户集。
Next we'll define the security roles for security roles are named sets of users that will have access to secure resources (like a servlet, JSP, EJB or SCA component) and methods.
注意，图7中出现了一个名为defaultRole的角色。如果用户不属于在多维数据集上具有显式授权的角色，则该用户被视为默认角色的成员。
Note that a role called default role appears in Figure 7. Users who do not belong to a role with explicit authorization on the cube are considered to be members of the default role.
在角色中添加或移除用户要比为单个用户重新创建单独的权限集更为简便。
It is easier to add or remove users from a role than it is to recreate separate permission sets for individual users.
