Top-Down and Botton-up

different perspectives SOA, the bottom-up approach, which is primarily IT driven.也即把现有的Java bean包装重用成Web Service等。

 

 And BPM, the top-down approach, which is business driven，一切从头开始设计，包括WSDL等。 

 

我喜欢这么一句话：

从技术(technique)的角度来说，用bottom up approach

从业务(business)的角度来说，用Top down approach
