Database Management Overview
Effective database management ensures data integrity, availability, and performance across the lifecycle of your applications. This guide covers essential concepts, best practices, and actionable steps to keep your databases healthy.
Best Practices+
• Use normalized schemas where appropriate.
• Implement proper indexing strategies.
• Regularly monitor query performance.
• Separate read and write workloads using replicas.
• Document schema changes and migration plans.
Backup & Recovery+
Schedule full backups weekly and incremental backups daily. Store backups offsite or in cloud storage with encryption. Test recovery procedures quarterly to ensure RTO/RPO goals are met.
Performance Tuning+
Analyze slow query logs, use EXPLAIN plans, and adjust indexes. Consider partitioning large tables and leverage caching layers (e.g., Redis) for high‑traffic reads.
Security+
Enable encrypted connections (TLS), enforce least‑privilege access, rotate credentials regularly, and audit all database activities.
