最后，模式的目标之一是提供一致性，以便最终能因为在设计中使用了模式而基于相同的一组需求得到相同的体系结构。
Finally, one of the goals of patterns is to provide consistency so that you end up with the same architecture based on the same set of requirements because you used patterns in your design.
这是弱一致性的一种特殊形式；存储系统保证如果对象没有新的更新，最终所有访问都将返回最后更新的值。
This is a specific form of weak consistency; the storage system guarantees that if no new updates are made to the object, eventually all accesses will return the last updated value.
最后，它可以使构架人员和设计人员能够看到完整的最终系统范围，改进架构和系统设计的健壮性。
Finally, it enables the architects and designers to see the entire eventual scope of the system, so far as it is known, facilitating robust choices for the architecture and system design.
