Hello I am creating a web application, for which users have to register on the site. The registration data(login name,first name,last name, password, etc.) are to be saved in xml format. Should I make one collection and save each user data as a separate document in that collection or should I keep a single document and append the user's data in that one document. I will be quering the whole user data on different fields like logon name and password to give user access to login the site. What should be the best design approach in this case?
