I need a little help. We want to connect our physical shop system with our virtual shop developed with woocommerce. So we need to be able to find where the SKU numbers are registred in the database so that we can do a batch process a few times a day to modify it as the products are physically sold (and not on the web).

But we haven’t been able to find out where that number is registered in the WP database. Could someone help us?
