XML Schema Design question

Question

Hello all,
I am a new to XML Schema design and struggling with designing my first XML Schema. Here is my problem.
I have almost 200 elements in my database which I have to use to design XSDs, I have customer name ( last name, first name, dob etc) and customer address ( office address, home address etc) and at the same time I have other player such as Patient name ( last name, first name, dob etc) and patient address( home address, office address).
And then we have some dollor related data such as patient insurance amount, copay amount , total amount and many more $.
What I wanted to know is that what would be best approach to design a XML schema for such kind of system, should I create one schema (xsd) for all the 200 attributes or I should create seperate schema for customers ( including names and addresses along with other dollor amount data ) and a similar xsd for Patient data. Some of the XML documents which I will create from these schemas would be based on customers and patient information both .
Thank you.

It's hard to tell what is the best design. But in order to simplify access to these data through other program APIs such as JAXB, you may start from defining objects such as the schema types/elements for customer, patient and the addresses
Then you can assoicate the related data to these object.
