I am a student at UT Austin and I have been assigned to a team project. Our assignment is to model a computer business that manufactures computers and sells them in the retail market along with other peripherials and software. Here is my question (I will use an illustration to detail):

Lets say you order 10 harddrives from a supplier and our company has allocted 7 to be used in assembly of computers and the other 3 will be sold via the retail market. How is each item defined in the system? Do the 7 go into Raw Materials and the other 3 go directly into Finished Goods and skip the raw materials table or do they go into raw materials and just move directly to the finished goods? How is all of this defined?

Here are the entities we have:

RAWMATERIALS - components used in making a PRODUCT. FINISHEDGOODS - a PART that is ready to be shipped as a PRODUCT. PART - the type of physical item that goes into a PRODUCT. INVENTORYITEM - represents the physical occurence of one and only one PART that may be offered as a GOOD.
GOOD - a subtype of a PRODUCT.
PRODUCTS - which are inventory items ready to be sold.

I got the above details from a book about data modeling, but I don't understand it all either nor do I know what I really need. Since this is the first db course I am taking the professor has dummied the project up so we only need to model this at a basic level so we do not need to get very complex with subassemblies etc.

We really need your help.

Thanks,

Gary Guion
