Hello,
I'm new to using oracle developer data modeler and oracle apex and I have very little knowledge of DB, so I apologize if I make big mistakes.
I plan to create a database around Movies, I realized the following physical model and I finally managed to create an app thanks to the help of some person on this forum.

What I would like to get now is the links between them, indeed I can create movies, actors, etc in my database but I have no idea how to establish the links between them,
I would therefore like to be able to have my tables linked so that I can make the selection of the type of actors playing in the Y movies or genre of the Y movies, etc ...
Do you know how I can achieve this in Apex?
