So I need a simple database schema for a DVD database. Here is my criteria: - database has to allow storage of customer details (names, etc.) - customer preferences (favourite genres, actors, directors etc.) - a catalogue of films held in stock ready for rental or borrowed - a table cross-referencing the DVDs to the customers who have borrowed them - a list of main actors linked to the list of films, genres, directors (to allow searching by category) etc. Can anyone help??
