WebService请求成功但未通过响应 - 最佳设计原则

Question

假设“Application1”想要对银行系统进行Web服务调用并更新记录。可能存在Http请求成功和Banking数据库以预期方式更新的情况。但响应失败可能是由于可能是通信错误。

Results : As the "Application1" has not received the response, it assumes that DB has not updated.

Possible Solution.
1. There will be a TimeOutException from the "Application1". Then make a  DBQuery check the record is updated or not inside the exception block. If it has not re-try it.

1. What happens if all re-tries does not receive the reponse. 
2. I see some theories related to Web Service Transaction , Service Ochastration. 
Any other better solutions. ?

Answer 1

更好的解决方案是使用消息传递系统。在您的情况下，WebService在性能方面将是昂贵的。
