Security administrators can control access to their databases at a level of abstraction that is close to the structure of their organizations.

安全管理员可以在接近于组织结构的抽象层次上控制对数据库的访问。

Note that if the structure itself has a more restricted access level, this automatically restricts access to its members, even if you adjust their access levels with the access modifiers.

请注意，如果结构本身具有限制性更高的访问级别，这会自动限制对其成员的访问，即使您使用访问修饰符来调整其成员的访问级别也是如此。
