Overview
Data Synchronization is critical for maintaining data integrity across distributed systems, mobile devices, and cloud applications. It ensures that changes made in one location are reflected in all other locations, preventing data conflicts and ensuring users always have access to the latest information.
Types of Synchronization
- One-way Sync: Data flows from a source to a target (e.g., backup).
- Two-way Sync: Changes in either location are mirrored in the other (e.g., file sharing).
- Real-time Sync: Changes are propagated immediately.
- Batch Sync: Changes are collected and sent at scheduled intervals.
Key Challenges
- Conflict resolution (when the same record is changed in two places).
- Network reliability and latency.
- Maintaining performance during high-volume updates.
