题目:

阅读以下关于面向服务架构的应用叙述,根据要求回答问题。
[说明]
某航空公司的主要业务系统(如订票系统、航班调度系统等)始建于20世纪七八十年代,之后随着信息化的进展,陆续积累了许多异构的遗产信息系统。这些系统部分采用了J2EE、.NET等技术进行开发,分布在不同的地理位置,采用不同的协议进行数据传输。近年来,该公司在企业集成方面也是煞费苦心,已经在几个主要的核心系统之间构建了用于信息集成的信息Hub(Information Hub),其他业务应用之间也有不少点到点的集成。尽管这些企业集成技术在一定程度上增进了系统间的信息共享,但是面对历史异构的遗产信息系统,企业的业务整合、功能整合仍是困难重重,主要表现如下。
(1)由于大部分核心应用构建在主机之上,因此Information Hub是基于主机技术开发,很难被开放系统使用。
(2)Information Hub对事件支持不强,被集成的系统间的事件以点到点流转为主,被集成系统间耦合性强。
(3)牵扯到多个系统间的业务协作以硬编码为主,将业务活动自动化的成本高,周期长,被开发的业务活动模块重用性差。
某软件开发公司承接了该航空公司应用系统集成任务,项目组经过多方讨论和论证之后,决定采用以面向服务为中心的企业集成技术,一步步解决该公司所面临的企业集成问题。

[问题3]
若项目组采用Web Service作为基于SOA集成方法的实现技术,请根据该航空公司目前的实际情况,用300字以内的文字说明系统应该分为哪几个层次,并简要说明每个层次的功能。

In the world today, all of the people need recreation(消遣). We can not work all the time if we are going to keep healthy and enjoy life.

Everyone has his own way of relaxing. Perhaps the most popular form is to take part in sports. There are team sports, such as basketball and football.
