On the afternoon of the 15th, at the China Database Society, I was lucky enough to listen to PowerDesigner's lectures. The speaker was Mr. Wang Xiaoyu. Ping, Mr. Wang is still very level, he can call the father of PD, but there is a little regret, it is that his lectures are not good, and many terms are not standard, which may be because of long-term in France Bar. Speaking of PowerDesigner, I have to admit that this is a very creative product. I admire Mr. Wang, I can make such a thing. PD covers all aspects such as business process modeling, database modeling, UML modeling, and all aspects are very close, and support for XML is also provided. Automatically generate code and database functions are also very fast. However, when it is supported by XML access to the database, only a language called XSQL (notified), without providing support for the standard XQuery, can't be said to be a regret.
