    2.Products have zero or more suppliers (computers can be made by store)
    3.The suppliers generate zero to many invoices
    4.The supplier invoices are monitored by one employee

    Customers:

    5.Products are sold to zero or more consumers
    6.Each customer contains one billing address

    Do you have a particular question or do you just want us to check your homework?

    I am looking to check it and I am looking for other opinions on it as well. I am hoping to achieve a better understanding of modeling by working with others. I feel it is better to work with several people rather than by myself.

    Thanks

    The project is not due until Monday afternoon.

    Here is a little more details about the database.

    The database is built on a simple brick and morter store.
    The store is only going to sell laptops, pda, servers, and desktops
    The store will not sell individual accessories.

    I am trying to keep it as simple as possible so I do not have to much to program. After all, this is not going to be a real database it's just a simple database for a project.
