I am a beginner in the database. I don't know how to design or solve the problem. Select "Major" and return to the curriculum. How should we design each table. How should I get back to the course schedule and generate a weekly schedule? Now I designed the system table (Department ID, Department name) professional table (Professional ID, professional name, department... my problem Beginner database, do not understand design, solution.Select "Major" an

It is now the 17th week of the semester in Monday, and the introduction of software engineering has been in session last week. After a semester of study, I learned a lot about the process of software development, especially team development, encountered a lot of previously never thought of problems, but also learned the team development needs to pay attention to things. Let me briefly say something about my feelings about this course and the improvement of my

。 trooped Harvest 有个队友结队编程，不仅让编写代码时工作量减小，也能学到更多的知识，有些各自懂得或者不知的知识都可以 在和队友的交流中清晰看见，互助互补，相互学习。Advice for learning younger brothers and sisters in school First of all, do not take the rejection before the beginning of the course, if the initial attitude falls behind the person, then it will have to spend more time and energy to make up for catching up. Although the course of study is hard, but no sweat how can be harvested, and what knowledge of learning is easy to grasp,

designing the system, we should learn to design and encode it in the form of interface, business, database operation and database.6. Deficiencies6.1 Because the curriculum design is oneself set the demand for oneself, the grasp degree is not good enough.6.2 Database design is not good enough, too many contacts6.3 Design of the overall idea is not clear enough, not fully grasp6.4 Do not know how to set up the corresponding model for each function modu

In the first chapter, we summarize the different performance of Java and other programming languages, and we have a preliminary understanding of Java. The second chapter discusses in detail how to download and install the Java Development Toolkit JDK and how to compile and run various types of programs: console programs, graph
