Question about Conceitual Database Model

  • Hi! I am creating a database for an ecommerce and among the entities there are Customer, Shopping Cart, Product, Inventory and Order. A customer adds products to a shopping cart and these products will be part of the order. But the products must be in inventory. What is the appropriate way to relate entities? Do Customer relate to Product too?

    Why?  In the long run, it's going to be less expensive and less worrisome to buy one, which will also take into acoount the FIFO nature of the inventory and contention between order for the same inventory, etc, etc.

    RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
    First step towards the paradigm shift of writing Set Based code:
    ________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

    Change is inevitable... Change for the better is not.
