Hello
I’m developing a webapp and i’m about to design the database, i came across this question.
Is it a bad design to have more then 1 link between 2 tables?
The picture i have posted is a very quick and small example just to make it clearer.
If i would like to display all the offers,i would like to insert also the products they are related to, in this case i could retrieve the product name by creating a product instance retrieved with the product id from the product id field in the offer object, but it would require more queries execution and more typing work, so i was thinking to include the product name directly in the offer so that i can simply retrieve all offers and eventually display the related product by browsing the DB with its product id.
Would you consider this a bad approach?
I have been looking around for cases like mine but i have only found approaches with 1 connection between tables (with unique id’s)
Thank you

    This is data denormalization. Don’t do it (in most cases). Design the tables correctly, let the database do the correct work with the correct queries. It will be much easier to maintain and work with over time.

    Use the ID in the offer table to lookup the product name in the products table.
