I am going to make a student management system using MongoDB. I will have one table for students and another for attendance records. Can I have a key in the attendance table to reach the students table, as pictured below? How?

推荐答案

MongoDB背后的想法是消除(或至少最小化)关系数据.您是否考虑过将出勤数据直接嵌入每个学生记录中?实际上，这是MongoDB的首选设计模式，可以带来更好的性能和可伸缩性.

The idea behind MongoDB is to eliminate (or at least minimize) relational data. Have you considered just embedding the attendance data directly into each student record? This is actually the preferred design pattern for MongoDB and can result in much better performance and scalability.

如果您确实需要高度相关和规范化的数据，则可能需要重新考虑使用MongoDB.

If you truly need highly relational and normalized data, you might want to reconsider using MongoDB.
