Consolidated database skill synthesized from architecture, admin, migration, optimization, and observability skill patterns.
When to Activate
- Choosing SQL/NoSQL database technologies and data models
- Designing schemas, indexes, partitioning, and replication patterns
- Planning and executing safe migrations with rollback
- Tuning query performance and fixing bottlenecks
- Defining backup, DR, monitoring, and operational runbooks
- Reducing cloud database costs without breaking SLOs
Do Not Activate
- Small app-only bug fixes unrelated to data/storage architecture
- Frontend-only tasks with no database impact
- Active incidents where immediate runbook triage is the only goal
Working Sequence
- Capture domain requirements and NFRs (latency, throughput, consistency, compliance).
- Select architecture and storage model (relational, document, key-value, time-series, hybrid).
