   model: 'StudentDataModel', proxy : {
      type : 'rest', actionMethods : {
         read : 'POST'  
         // Get or Post type based on requirement
      },
      url : 'restUrlPathOrJsonFilePath', 
      // here we have to include the rest URL path 
      which fetches data from database or Json file path where the data is stored reader: {
         type : 'json',  
         // the type of data which is fetched is of JSON type

   }
