* 分级
* 松散耦合
* 可重用的服务
* 服务接口设计管理
* 标准化的服务接口
* 支持各种消息模式
* 精确定义的服务契约
引用别人的话"它不是一门技术,更不能把它刻录到光盘去卖什么的..它提供的是一种思想!就想OO思想一样!
IBM WebSphere Integration Developer, Version 6 software is Eclipse technology-based tooling designed to enable you to rapidly assemble business solutions based on a composite application development framework and using minimal programming skills.
Its graphically rich interface allows developers to create composite business applications by wiring service components with minimal skills and agnostic of underlying programming implementations. It has fully integrated testing, debug and deployment environment that allows you to easily deploy to WebSphere Process Server. Once deployed, you can dynamically change and adapt to changes with its rich features, such as business rules, selectors, and state machines.
WebSphere Process Server includes three layers:
SOA core
Supporting services
Service components
Role resources matrix
Duration matrix
Availablity matrix
Decision probabilities
