    I'm not going to do your homework for you. It would be a disservice to you as well as the software engineering field in general. However, I will give you a hint. First, decide what objects you will need. A good starting place would be to pull out all of the nouns in the requirements description and use that as a starting place to define the basic objects your architecture will use. In this case I would use a "product" class that contains members for each of the attributes you need to keep track of (Hint #2: members can be objects as well.). Create a new instance of the product class and populate its members each time a new item is put in the database. Store these objects in the data structure of your choice. With a max of 10,000 items I think a btree using the product ID as the unique identifier would be a good choice.

    First of all a 4-digit barcode is only going to get you 4! (or 24) unique items. You'll need to increase your barcode digits to 7 (5040) or really 8 (40320) to get 10,000 unique items... As for the actual software, I'd try Planet Source Code... Planet Source Code: http://www.planetsourcecode.com/vb/default.asp?lngWId=3 Try searching for inventory programs...
