title: CouchDB: Single Page Web Application accounts without middleware
body: <p>Is it possible to implement Single Page Web Application that would have sensitive data, e.g. accounts, with address etc, without middleware?</p>
  
  <p>I've been evaluating CouchDb, as the best applicable, because it allows to implement author only updates. But is it possible to implement author only views with it? </p>
  
  <p>I.e. is it possible to overwrite special _all_docs view, at least?</p>
  
  <p>Or is there any other permissions ware data storage, including and not limiting to other (NoSQL) databases?</p>
  
  <p>Thank you.</p>
