Excuse my beginner question. ...Assumptions. I have two entities in my domain model, "member" and "project". Each possesses multiple attributes. What we want to do I want to check which members are participating in which project on the homepage. The reverse is also true How can we achieve the above? Do we need to create intermediate tables on the domain model? If so, I would appreciate it if you could also tell me how to create it. Translated with www.DeepL.com/Translator (free version)
