I’m currently practicing developing a project using a microservice architecture, which includes:
• Authentication: Manages user authentication, authorization, and user information
• Course: Manages course-related data
Each service has its own separate database. So how can I handle many-to-many relationships across services? I would appreciate any advice or suggestions.
Sincerely, thank you!

Can you explain how you want to relate these two services and data etc? (will help anyone trying to help you 🙂 )

Here for example I have two services auth and course, auth will manage users and roles (admin, teacher, student ....), now I want to get all courses of a student
for example so now I am calling api to service course with student id, So is there any better way! remember that each service manages separate database

Are the microservices completely separate projects, or is it modularized monolith?
And what do you mean by "many-to-many" relationship? A database query runs on one specific connection, and it can't reach across to a different connection, even if it's just a different schema on the same server. BelongsToMany relationships use joins to identify related rows, so it needs to have all the tables available.

I’m currently practicing designing completely separate projects following the microservices approach. For example, as mentioned above, when I want to retrieve the courses of a student, I’m calling the Course service via an API. So my question is: are there any other ways to handle this kind of query?
