Databases

Databases store and organize structured data so it can be reliably queried, updated, and secured for analytics and applications. They matter because sound database design improves performance and data quality, reduces duplication, and enables traceability through controlled schemas and access rules.

Design Normalized Schemas With Primary/foreign Keys, Constraints, And Indexing Strategies Aligned To Query Patterns.

Write And Tune SQL Queries, Views, And Stored Procedures To Support Reporting And Application Workloads.

Implement Role-based Access, Encryption, And Backup/restore Procedures To Protect Data And Meet Compliance Needs.

Diagnose And Resolve Integrity And Performance Issues Using Execution Plans, Logs, And Monitoring Metrics.
