如果你必须要在一个时间内构建一个子系统，这样的体系架构将迫使你首先构建底层的子系统，然后构建越来越上层的子系统。
If you had to build one subsystem at a time, such an architecture would force you to build the bottom layer subsystems first, and then go higher and higher up.
然而，如果你有一个分层的体系架构，在上层的子系统依赖于底层子系统的能力，这种方法将不能够很好的工作。
However, this approach does not work well if you have a layered architecture, with subsystems in the upper layers dependent on the capabilities of subsystems in the lower layers.
