Student tracking system

Hello everyone, I am looking for a student tracking system that works in SharePoint Online.  I need it to track a student, name, parents, grade, location, adviser (could be multiple of these ) etc. with a one to many relationship to classes (class, location, grade, etc.) and to communications (date, adviser, talk to (student and/or parent), notes/comments, and how communicated).  Are there any third party add-on's for SharePoint that would handle this?  Or any ideas/examples on how to approach this using SharePoint Online modern list is greatly appreciated?

Thank you!
