Breeze will solve all my problems but I'm pretty stucked at the beginning and the doc is a lot confused, at least to me. I just wanna to know how to get data from a web service, follow some question:

What scripts that i need to include? just breeze.js or q.js and angular adapter too?

On brezze doc theres an example to retrieve "employes" like this:

manager.executeQuery(breeze.EntityQuery.from("Employees"))
       .then(function(data) { $scope.employees = data.results; });

What this ".from("Employees")" does? I'm dealing with web service this "Employees" should'nt be an URL?

Maybe you should consider Restangular, it integrates well with angular and the doc is great github.com/mgonto/restangular - kfis
restangular deal with localstorage too? - Daniel Faria

They loaded

 <script src="/Scripts/jquery-1.8.2.js"> 
 <script src="/Scripts/angular.js"> 
 <script src="/Scripts/q.js"> 
 <script src="/Scripts/breeze.debug.js">

I think that

    var manager = new breeze.EntityManager('api/northwind');

initialises the base url.

so 

  var query = new breeze.EntityQuery().from("Employees");
  manager.executeQuery(query)

ends up in a request to GET api/northwind/Employees

For your question if Q.js is needed: By default, Breeze asynchronous methods return Q.js promises not AngularJS $q promises. You have to include the Q.js library in your client stack.

You can switch to Angular's $q promises by including "breeze.angular.q.js" in your application and telling Breeze which $q instance to use. Then you can remove the Q.js library from your application.
