Question

I got one order table, when user come to the store they could purchase more than one item for example. may i know what is the best practices to perform such record action ? is that each item order one row in order table or mix all into one row in order table ?

Let say, Customer A purchase 3 items from store. then will be 3 row in order table ? or 1 row in order table with all details and separate order with delimiter ?

My designed structure is like this::

tblOrder
    OrderID (Primary Key)
    UserID
    TotalPrice

tblOrderItem
    OrderItemID (Primary Key)
    OrderID (Referencing tblOrder)
    Quantity
    ItemID (Referencing tblItem)
    TotalPrice 

Is this correct ?

Answer 1

I will suggest you to maintain 3 rows, because it will be easy for you to maintain further.
