Study Notes on j2-based learning platform (2)

This is a very simple example for students, because I have no mobile devices at hand and I will not use any simulators at that time .., therefore, the debugging is successful at the current level. The database uses SQL Anywhere, and it feels good. Because I have never studied it before, I think it is convenient. I will explain how to use SQL Anywhere in detail next time, but I also studied it in Chinese documents. If this guy wants to be lazy and doesn't want to find him, I will add my sans_reason@hotmail.com and I will send it to you. Haha
