ＥＲＰ的发展，从ＩＴ技术的角度看，它基本经历了三个阶段：第一阶段是主机／工作站技术阶段，第二阶段是客户机／服务器技术阶段，第三阶段是互联网技术阶段。如果说第一阶段向第二阶段的转变，只是一个技术平台的改变，那么第三阶段的变化不仅是技术平台的转变，更是业务平? ERP development, from the perspective of IT technology, has basically gone through three stages: the first stage is the host / workstation technology stage, the second stage is the client / server technology stage, the third stage is the Internet technology stage.
