Model Structure

Model
  * must have id column

ModelObservable <- ModelDao._allchanges

ModelDao
  -> insert
     update
     delete
    -> notify ModelObservable/ContentProvider
     
  -> query => Model
  
ModelTrans <- Model
  => ModelObservable

ContentProvider <- ModelDao._allChanges
  -> insert
  -> update
  -> delete
    ->notify Cursor,notifyChange(@NonNull Uri uri, @Nullable ContentObserver observer)
  -> query -> ModelDao.query -> Cursor,setNotificationUri(ContentResolver cr, Uri uri) => Model
