How to avoid sending all related objects in update ??

Data Service

Hi -

I have something like below in DB:

Object_1 -> Object_2 -> Object_3 -> Object_4

Now, assuming I have all above objects in memory - and now if I do update on Object_1 (in android app) - how can I avoid not sending all other related objects (Object_2, _3, _4) over network, as they have nothing changed ??

I want to optimize my Object_1 update time - thus asking this.

Thanks.

Couple variants:1. do not load related objects.

  1. create new Object_1 put objectId to this object, put changed values and save new object

Thanks. Second option worked fine - just that I had to put all values (like string values that are not changed) except the related objects.
