Example Concept: Offline data synchronization in mobile apps often employs a pattern where local data is stored using a database like SQLite or Room (Android) or Core Data (iOS). When connectivity is restored, a background service or task synchronizes the local changes with the server. This process includes conflict resolution strategies, such as last-write-wins or merging changes, to ensure data consistency. Frameworks like Firebase or Realm can also facilitate real-time data synchronization and conflict management.
