We have been working on the student information management system for the past few days, and our VB work has come to an end. In fact, there are still a lot of things in VB, just as the teacher said a course could not be all done, that is impossible! It is good to reach a suitable level. Think about the student information management system we are currently working on. Isn't it also consolidating VB knowledge. On the basis of consolidating VB knowledge, I learned how to use VB to connect to and operate databases.
Two days of coding and two days of debugging are basically done, and the remaining days continue to look for bugs. I feel like a bricklayer, where vulnerabilities are blocked. While chatting with the glory, I said that the thing we made is like a chicken nest! Not even a chicken nest. It can be regarded as a straw nest at most !!!" Me: "..."
It seems that there is no good design, and the debugging work in the later stage is too cumbersome. It is often a "Pull-and-pull ". Design is too important!
After all, you have to ask me how I feel about the database. I am sorry cannot say one, two, or three in the system. However, the student management system has a certain understanding of the database. Today, I am going to watch the video. The "system" learning database ......
Tables in the database are associated (nonsense !), As for how to operate the data (add, delete, modify, and query), the record set is required. You still need to go to the book or go online to check the statements involved. I don't have to worry about it. In fact, my heart has long been like an ant on a hot pot. It's more like a hungry wolf! That's terrible!
The road is long, and I will go up and down.
