A family of Microsoft relational database management systems designed for ease of use.
There are two versions of the Northwind Template, one for beginners, one for developers.
Inventory is more fully handled in the developer version, so I recommend that you choose it.
BTW. You are also asking for help with completing an assignment in a course you are taking. I would urge you to think about that differently.
If you allow someone else to give you the results needed to get a grade in a course, you have short-changed yourself. By not digging out the information and learning it, you are giving up the chance to, well, learn it. Invest in yourself by studying and reading and trying out the things you need to know to complete the assignment.
Most of us already have some level of experience, so reiterating all of that knowledge for you does none of us any good either.
