Babu,
URIs uniquely identify documents in a database, similar to a primary key in a
relational database table. I’m not sure about your use case, but, like Mike
outlined, I’d suggest creating the user document XCCDemo/user1 and the
associated image at XCCDemo/user1/image. There are various ways you can
associate the image with the related users. You could put both of those
documents in the same collection (user1) or directory (as Mike indicates
below). You could also put a reference to the image URI in the user1 XML
document. If you could provide more details on what you’re trying to do,
someone on the list might be able to give you some more specific advice.
