What is the (best) flow for using UploadThing inside my react hook form?

When the form is submitted, I would like to create a record in the database with the associated files added by the form. Question 1: Does it make sense to have an extra table in the database called files with the fields: id, key, url, name, size so I can link multiple files to other records with many to one/many relationships. Question 2: What is the correct order for my use case? For example, should I upload the files first and then set the file keys as form values or is there a better way? Thank you in advance!
