FINANCE HOMEWORK HELPPPP...

I have sent the document and you already looked at it. This is basically an E-R diagram based on the to-be process explained in the document. I have three processes.

1- order fulfillment process. 

2- IT purchasing process.

3- Manufacturing process.


I have done already these processes.
