Optimizing database queries reduces response time and battery consumption. Techniques include:
Using indexes on frequently queried columns.
Avoiding SELECT * statements; specify needed columns.
Limiting result sets with filters or pagination.
Caching query results where appropriate.
Using prepared statements to speed mobile database repeated queries.
Optimized queries improve app speed and ensure smooth user interactions, especially on resource-constrained mobile devices.
Mobile Database Security: Encryption Techniques
Encrypting mobile database data protects sensitive information both at rest and in transit. Common techniques:
Full Disk Encryption: Protects all data on the device.
Database-Level Encryption: Encrypts database files or specific tables.
Field-Level Encryption: Encrypts sensitive fields such as passwords or personal info.
Transport Layer Security (TLS): Secures data during network syncs.
Combining these layers ensures comprehensive protection against data breaches.
