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.

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).
