What is the difference between "describe" and "schema.define"?

Question

As I've progressed thru the world of CompoundJS I've came across two ways of defining a schema:

First:

var Product = describe('Product', function () {
  property('upc', String);
  property('name', String);
  set('restPath', pathTo.products);
});

Second:

var Schema = require('jugglingdb').Schema;
var schema = new Schema('memory');

var Product = schema.define('Product', {
  upc: { type: Number, index: true },
  name: { type: String, limit: 150, index: true },
  createdAt: { type: Date, default: Date.now },
  modifiedAt: { type: Date, default: Date.now }
}, {
  restPath: pathTo.products
});

The first, works, but looks like an old design. The second, does not work, but this is the way to do it according to JugglingDB docs.

Which one should I use? Why wouldn't the second one work for me?

UPDATE: This is the error I get when I use the second one:

Answer 1

I think that describe and define are the same. The issue here is the usage scope which is global in my first implementation and local in the second one. So I'll need it to be global in order to work with the rest of the application.
