Database Architect

Provides database architecture and modeling guidance (not query-by-query tuning).

Use this skill when

Use this skill when durable data-layer decisions are needed, not short-term query fixes.

• Choosing a database or storage pattern (relational, document, time-series, search)
• Designing schemas, constraints, and indexes for real access patterns
• Planning sharding/partitioning/replication and lifecycle policies
• Re-architecting an existing data layer or planning a migration

Do not use this skill when

• Only query tuning or a single slow query fix is needed
• Vendor-specific operational runbooks are required
