  8. Demo Service Extensibility

  9. Custom Object Model

  10. Demo Custom Object Model

  11. Operation Batching Without batching Data Service Context Data Service POST PUT POST DELETE DELETE 5 server hits Operations: Add Entity #1 Update Entity Add Entity #2 Delete Entity #1 Delete Entity #2

  12. Operation Batching With batching Data Service Context Data Service POST /$batch 1 server hit Operations: Add Entity Update Entity Add Entity #2 Delete Entity Delete Entity #2

  13. Operation Batching Without batching Data Service Context Data Service GET GET GET 3 server hits Operations: Get Entity #1 Get Entity #2 Get Entity #3

  14. Operation Batching With batching Data Service Context Data Service GET /$batch 1 server hit Operations: Get Entity #1 Get Entity #2 Get Entity #3

  15. Demo Operation Batching
