How is this data is saving in back end in Ember

Hi there ,

I am new to Ember ,though I went through many of its examples with fixture data and also with the Json data. Its been very well "Getting Json Data ",but its being heck for me to save somewhere .i.e

  1. I don’t know where to save data .

  2. I don’t know how to save data .

Basically ,I guess I don’t know whole concept of “Saving Data into DataBase”

Even though the answer is silly ,please let me know. Thank in advance.
