问题:

某软件公司承担了某大型企业应用系统集成任务,该企业随着信息化的进展,积累了许多异构的遗产信息系统,这些系统分别采用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。企业要求集成后的系统能够实现功能整合,并在组织现有功能的基础上提供增值服务。为了按时完成任务,选择合适的企业应用集成方法和架构非常重要。项目组在讨论方案时,提出了两种集成思路。
①刘工建议采用传统的应用集成方法,将应用集成分为多个层次,并采用消息代理中间件连接遗产系统。
②王工建议采用基于SOA的方法进行应用集成,将现有遗产系统采用Web Service的方式进行包装,暴露统一格式的接口,并采用企业服务总线(ESB)进行连接。
项目组仔细分析比较了两种方案的优点和不足后,认为刘工和王工的建议都合理,但是结合当前项目的实际情况,最后决定采用王工的建议。

请分析比较两种方案优点和不足,完成表12—12中的空白部分。

     Giving someone good news is easy, but what about bad news? Are there any good ways to give bad

news without making people too upset? The following steps might help:

     Say something positive. Try to start or end the conversation with some good news, so that it's not all bad.

For example, "You did very well in the interview, but unfortunately we've given the job to somebody else."

     Prepare your listener for the news. Use phrases to introduce what you're going to say, like "Unfortunately,....", "I'm really sorry, but..." or "I'm afraid I've got some bad news." This gives the listener time to prepare

for what you' re going to say.

     Try to give a reason. People like to know why things go wrong. Try to explain the decision. If someone

doesn' t get the job, can you explain why? If you have to cancel an appointment, try to give a reason.

     Use a soft tone of voice. If you're giving someone bad news, try to use a soft, calm voice to make your

sound kind. Say things to show you understand, like "I'm really sorry." or "I know this must be disappointing."
