摘要
传统两层模式已无法适应开放系统中实现大规模的关键业务的要求,以交易中间件为基础框架的多层分布式体系应运而生,它支持分布计算,提供跨网络、硬件和OS平台的透明性的应用或服务的交互、且支持标准的协议、接口等。
The traditional two-layer mode has not been able to adapt to the requirement of realizing large scale and important business in an opens system,the multi-layer distributed system which based on the middleware is devised.This system can support the distributed computing,supply transparent application or alternation of service among net-work,hardwares and OS flat port,and accommodate to standard protocols,interfaces and so on.
