title: What kendo datasource schema-model are all about?
body: <p>I tried to explore <a href="http://demos.telerik.com/kendo-ui/grid/local-data-binding" rel="nofollow">this example</a> on dojo
  And then, I just noticed these lines of code:</p>
  
  <pre><code>      dataSource: {
              data: products,
                  schema: {
                      model: {
                         fields: {
                              ProductName: { type: "string" },
                              UnitPrice: { type: "number" },
                              UnitsInStock: { type: "number" },
                              Discontinued: { type: "boolean" }
                          }
                       }
                   },
  </code></pre>
  
  <p>I tried to delete the whole <code>schema</code> thing and it works just fine. It doesn't affect the columns and fields and even the loading performance.</p>
  
  <p>Now I wonder the purpose of that thing. I do some quick research, and I found nothing specific. </p>
