    Please Please help me with this easy question

    Dear DBF users,

    My name is Rich, I just started studying IT on the Hanze University and have a test in 5 hours from now and I can't find the anwser to my question.

    I hope you can help since this is very basic DB knowlegde.

    I have the following ERD (entity relations diagram):

    http://i19.photobucket.com/albums/b186/seperti/erd1.jpg

    Does this diagram mean that a sale can only contain min AND max 1 product?

    for example:

    let's say we have 2 products:

    product Number: 001 | product Name: headphones
    product Number: 002 | product Name: laptop

    can order 1: only contain headphones (unlimited quantity) OR laptop, but not togheter in the same order?


    thanks alot for your time!

    I appreciate it!

    Regards,

    Rich.

    Yes, it all all our fault that you failed.
    You can lead some folks to knowledge, but you can not make them think.
    The average person thinks he's above average!
    For most folks, they don't know, what they don't know.
    Don't say, show. Don't promise, prove.

    let's see... you post a request for assistance 5 hours before your test...

    and then you wait 2 weeks to complain about failing...

    dude, you have serious time management issues

    Mission accomplished.
    If it's not practically useful, then it's practically useless.

    It is because he got the results now (i.e. 2 weeks after taking the exam). Hope dies last (but it died this time, anyway).
