Overview
The database stores the users' characteristics (ID, IP, time of log in, DNS, etc.) in the 'store users' table
It also preserves all unordered shopping carts in the 'store shopping cart' table.

In time, the database may increase in size and it is recommended to delete these records monthly. After cleaning the database, all unordered shopping carts will be erased, and only the last month users' characteristics will be kept!
