How to fetch associations #382

So I have developed an app with the feathers framework. I have a hook attached to a database service that I want to access data from another service. Is this possible, and easy? I want that service to be able to access several neDB files. How do I do this?

'use strict';

module.exports = function(options) {
  return function(hook) {

    // access other db files here and get data

    hook.data = {
        putDataHere: newData
    };
  };
};
