title: "Global" core data in Document-Based App
body: <p>Ok so I have a document-based app, which is running pretty well so far. It essentially represents a course/camp that students would attend. So each document represents a separate course… everything is fine there, I use core data to add and remove students/teachers and a bunch of other stuff.</p>
  
  <p>But here is my question, I want the user to be able to add Schools to the application and have access to them in any document they might create, note the student and the school have a relationship between one another.</p>
  
  <p>I have done some reading on "Global Persistent Stores" but I'm not quite sure if thats what I need. Can anyone point me down the right road.</p>
  
  <p>Sorry for the long question and thanks for any help you give.</p>
