Mobile Database Sync: Resolve Conflicts Explicitly
Two offline devices edit the same record and last-write-wins silently loses work. This guide gives you a small, testable way to approach the issue before changing a live system.
A practical workflow
- Give operations stable IDs and retain version information for conflict detection.
- Define per-field or user-assisted resolution for data that matters.
What to check
Clock timestamps alone are unreliable when devices have wrong time. Compare the result with the original problem and record what changed. If a measurement or test does not support the change, revisit the assumption rather than adding more complexity.
Keep the experiment small enough to reverse. Document the starting state, the change and the result so another person can repeat the process. Product menus and versions can change, so check the current documentation for your environment.
