I'm sorry, but the question is a bit vague. I'm assuming you're tasked with doing this at work and you've never done it before.
First, you need to differentiate between new objects for the database and changes to existing objects. For new objects, you only need the business requirements to begin the modelling process. For changes to existing objects, you need the business requirements and you'll need the previous business requirements as well as some type of dependency tree that shows the objects, code, and applications that you might be affecting with a given change. Then you can begin modelling an impact statement that shows the things that will be affected by the changing objects.
That's a general approach. If you have specific issues or needs, you'll need to outline them.

If this is homework/exam question, you need to do some more work, or show us what you think needs to happen to answer the question. We are happy to help you, but we should not be doing the work for you.
