Semantics

Determining the data in the database by the semantics of the database.

1. There are a number of majors in the school. Each major recruits several classes each year, and each class has several students; (construction professional table, student table)
2. Each major has its own teaching plan, which stipulates the nature of the relevant courses of the major (compulsory or elective) and the semester of the lecture; (constructing the teaching schedule, curriculum)
3. A teacher can bring classes to multiple classes, but can not bring multiple classes to a class; (constructing teacher tables, and a many-to-many relationship between teachers, students, and courses)
4. One course allows students to make up for one test at a time; students are expelled from one of the following conditions: 15 credits for failing compulsory courses or 20 credits for failing elective courses; (constructing transcripts, constructing compulsory courses Passing the view of students who pass the elective course and failing students)
