Hi, I'm a newbie in web programming and I just finished my first website in my professional practice and the company was satisfied, only my question is for example I have my BD which has a table related to a table. sale, the doubt in particular if it is correct to remove the product from my product table or I can only unsubscribe it, since as my table is related to products I do not know if it causes any error or what happens with that sales notes that already are old and have a product associated that is no longer for sale that is done in that case you have to eliminate the product from my product table permanently or just add a field in my product table that is called active or inactive so that it does not show if you do not want to sell that product in the future, greetings!
