Request advise on wishlist

I would like to make a wish list for customers. I know I can do it by adding an extra table to the database for example customerProducts and when a button is pressed add the values from the customer and the product to that table. I was only wondering if there is someone who can advise me on another approach without database involvement.

Thank you all

I was at first thinking about cookies but after some consideration and your question I stick indeed with the table approach :slight_smile: Thank you rudy

where did you want to store the information, if not in the database?
