i am a .net user so i am unfamiliar with not using a foreign key inside of the database.
On my WP application, user's are able to create videos on the application, the videos are stored on a different server, and I am just using a simple UI to gather video information such as src value and title of movie, ect...
I am adding a custom table to the WP DB, "user_video" it will hold the user's video data.
How does Wordpress create a child-parent relationship between tables? (E.g. user & usermeta) I am just wondering how I can create a child table to hold video data for that specific user?
