What training brings happiness

• List item
• Just started to pay more attention to theoretical study in school , It feels boring , Later, I learned that there is a training or course design every academic year .
  I still remember that the first training was taught by the teachers in Beijing Darnay JAVA For the crawler . It gives me the feeling that the computer is amazing, great and has a sense of achievement . Just a few lines of code can save all the novels and pictures on major websites to the computer . Although it's not clear what the code means , But in the process of running the code, I fully realized the happiness of tapping the code .
  The second training is data structure binary tree training . Use C、C＋＋ perhaps java Realize the traversal of binary tree , Recursive traversal and non recursive traversal , Make use of the characteristics of stack and queue to perform pre order 、 Middle preface 、 After the sequence traversal . Then use the index to query . In the whole process, we mainly focus on our comprehensive quality , Poor course design requires good professional skills and comprehensive ability to deal with and solve problems , You can't be defeated by a small setback .
  This year's training is database , involves
  SQL server,mysql The realization of a database management system 、 Delete 、 Change 、 Check function , The library management system I chose also needs to consider the two aspects of facing students and administrators . I think the most difficult thing is how to realize the relationship and interaction between entities or tables . No matter how , Can't change my love for computers , There is nothing more relaxing than typing on the keyboard .
  Hand in your homework another day .
