Shopping cart table

How did Infusion saves data of a shopping cart when an user has just added a product to cart and not purchased it yet?
I looked at Table Schema Documentation - Keap Developer Portal but only table that looks like this is “job” table but how multiple itmes of a cart will be related if this is right table

any pointer will really help

There is no exposed table for this. You can only modify information on the shopping cart by using url params.
