You are developing an occasionally connected smart client used by service technicians. The application downloads a dataset when online. When the application is offline, the application must persist changes made to the dataset. When the application returns online, the application must upload local dataset changes and refresh the local dataset.

You must choose a robust solution for local data persistence and merging. Your solution should require minimal client memory.

What should you do?
