My question is that, if we enter the Student Information, Class Information, Session, and Result if Student Pass in 2020 Session, How to keep the Record of session and progress of a student each year. 还是我需要重新输入？

Answer 1

您的 session 表应为每个 Sessional Year 包含多个条目，主键为 session Id。

结果表应该有 studentStudyId 和 sessionid 并且它们形成复合主键。通过这种方式，您可以存储每个学生所有学期的结果。

提供的对象的数据模型如下，每列的主键可以自动递增。
