Push data flow:

Step	client App	server

When each flow succeeds in the API call (which means server has been updated for individual entry, the "dirty" flag will be removed. New Data = all entries with "dirty" flag. Push new data to server. Include the device key (or device id).
2		Receive the new data.
3		Generate a timestamp (e.g. date time now) and stamp it to the data.
4		Save data to the DB together with the device key.

Pull data flow:

2		Receive the client timestamp and client device key
3		Query data from DB with this filter: db timestamp > client timestamp db device key != client device key Send the resulting data back to client
4	Receive resulting data from server
5	if record match (e.g. ticket id, customer id) with local storage update the record locally. Otherwise, add the new record locally.
