Hello everyone, how are you?
Well, I'll be brief and I'll doubt it, because I'll post here 2 images, it's a non-standard table template scheme sent by my college professor, and the other one I created using my knowledge, and in fact my model is almost ready and I made using the program BR.MODELO, there I had some doubts of the tables, if I created their cardinalities, tables and foreign keys correctly, it follows the images below:

Then if you have something wrong like tables, foreign keys or cardinalities just help me identify the errors, Thanks!
