Data Synchronization
Data synchronization is the process of ensuring that data in two or more locations (e.g., databases, devices, or systems) is consistent and up-to-date. It involves replicating changes made in one location to others, often in real-time or at scheduled intervals, to maintain data integrity across distributed environments. This concept is fundamental in modern computing for enabling collaboration, backup, and seamless user experiences across multiple platforms.
Developers should learn data synchronization when building applications that require data consistency across multiple devices (e.g., mobile apps with offline capabilities), distributed systems (e.g., microservices architectures), or collaborative tools (e.g., real-time editing software). It is essential for scenarios like cloud-to-local sync in productivity apps, database replication for high availability, and IoT systems where devices need to share state updates reliably.
