Please I need a help on something, I am new on elxir/phx. I came from the background of Core Php coding style without framework trying to lay my hands on elixir/phx tech. I have a project that will require user authentication table, users table (This will hold more info about the use) and also user roles/permissions table ( that’s activities a user can do or cannot do on the app), but I am having challenge on how to manage this tables, So my question is, is it better to have the tables managed separately or should I merge all of them into one table? Thank you guys in advance.
