Different mobile database systems adopt various consistency models ranging from strong consistency to eventual consistency. Strong consistency guarantees immediate visibility of data changes across all devices, essential for transactional apps. Eventual consistency allows temporary divergence but ensures data convergence over time, suitable for offline-first apps. Understanding and choosing the appropriate consistency model helps balance performance, availability, and user experience.
Conflict Resolution Strategies in Mobile Databases
When syncing data between mobile devices and servers, conflicts mobile database may arise due to concurrent edits. Mobile databases implement various conflict resolution strategies, such as last-write-wins, manual merge, and automatic merge algorithms like CRDTs. Choosing the right strategy is crucial for data consistency and user experience.
Encryption Techniques for Mobile Databases
To protect sensitive information, mobile databases use encryption both at rest and in transit. Techniques include AES encryption, hardware-backed key storage, and end-to-end encryption. Proper encryption safeguards user data against theft, unauthorized access, and breaches, complying with data privacy laws.
