How do you choose peacetime
Between foreign keys and table links
It depends on the situation. For example, you have one table to store product data and another table to store product types. There is nothing to use foreign keys at this time.
If you have a table to store order data, another table to store customer information, a table to store product information and a table to store store information, it will be slow to use foreign keys at this time.
I don’t know much about it either. Look at the bottom and translate it for you if necessary.
