Definitions for Courses and Classes

[kyukyukyu]

• Course (과목): An entity which is identified with course_no. Semantically, a course is a unit of teaching that typically lasts one academic term, is led by one or more instructors (teachers or professors), and has a fixed roster of students. (Source: Wikipedia)
• Class (강좌): An entity which is identified with class_no. There are one or more classes for one course. Semantically, a class is a group of pupils or students who are taught together. (Source: Naver Dictionary)
• Placement Required Course (필수 배치 과목): A course which the placement of at least one class of is required for the combination.
• Placement Optional Course (선택 배치 과목): A course which the placement of at least one class of is optional for the combination.
• Fixed Class (확정 강좌): A class that should be placed for every combination, which means any other class of the same subject should not be placed.

I think we should get rid of 'Fixed Class', because users can get the same result by just adding only one class of the course.

Instead, 'Preferred Class (우선 배치 강좌)' can be suggested. 'Preferred Class' is a class which timetables with should be listed first in the result.

The difference from 'Fixed Class' is that the classes that are of same course with a 'Preferred Class' can be placed. However, the timetables with other classes of the course is listed later than the timetables with a 'Preferred Class'.

[kyukyukyu]

Don't define 'Preferred Class'. Instead, just follow the order of classes and courses in the class cart when creating new timetables, so that users can set the overall priorities of classes and courses by sorting them in the class cart UI.
