I went to IBM's SOA WebSphere for the day before yesterday. After listening to their introduction, I have a deeper understanding of SOA. In order to support the SOA framework, these tools make SOA simpler. Simple . In this competition, we have to make full use of these tools. Because I was busy with the test, everyone didn't have much energy to do this SOA. I don't know why IBM makes this game at this time. Now everyone is finished, and finally I can do my best to do this. Since we started late, the work done in the previous period is not very much, so the current task is heavy. However, we believe that it will be able to complete the scheme as scheduled. Let us work together.
