What is better to use on the backend with a bunch of rect when creating a web application for a schedule at the university?

Question

Database

Hello! Now I’m doing a graduation project, a schedule for the university, I almost don’t understand the backend, a question has arisen, tell me where to dig, where and how to store data, such as the schedule of students and teachers? What database is better to use and how to get data from it? For now, I imagine it this way, I choose a course and a group, and the appropriate schedule is given to me from the backend, tell me the options for how this can be implemented, some examples or my own versions of how to do this in the best way. Thank you very much in advance :)
