DB Design
Good OLTP design balances integrity, write paths, query patterns, and evolution—not “third normal form everywhere.”
When to Offer This Workflow
Trigger conditions:
- Greenfield service schema or major new domain
- Performance or integrity issues from ad-hoc tables
- Multi-tenant isolation questions
Initial offer:
Use six stages: (1) domain & access patterns, (2) entities & relationships, (3) keys & constraints, (4) normalization trade-offs, (5) indexing & performance, (6) operations & evolution). Confirm RDBMS and scale expectations.
Stage 1: Domain & Access Patterns
Goal: List critical queries and writes: QPS, joins, filters, hot rows.
Exit condition: Top access paths ranked by business importance.
Stage 2: Entities & Relationships
Goal: ER model; cardinality; optional vs required relationships.
Practices
- Clear table names; avoid opaque “data” blobs unless documented
Stage 3: Keys & Constraints
Goal: Primary keys (surrogate vs natural); foreign keys with explicit ON DELETE policy; unique constraints for business rules.
Multi-tenant
tenant_idon rows that need isolation; composite keys or indexes as appropriate
Stage 4: Normalization Trade-offs
Goal: Normalize to reduce update anomalies; denormalize read hotspots with documented trade-offs.
Stage 5: Indexing & Performance
Goal: Indexes serve real queries; watch write amplification and index bloat.
Stage 6: Operations & Evolution
Goal: Migration strategy (expand/contract); backup/restore; PII columns flagged.
Final Review Checklist
- Access patterns drive schema
- Keys, FKs, and constraints explicit
- Multi-tenant isolation if applicable
- Normalization decisions justified
- Index plan aligned with queries
- Migration and ops considerations noted
Tips for Effective Guidance
- NULL semantics and defaults matter for bugs and migrations.
- Pair with db-migrate for online schema changes.
Handling Deviations
- Document stores: embed vs reference with consistency story.
- 确保已安装 OpenClaw(本地或 Docker 部署)
- 在对话框中输入安装命令:
/install db-design - 安装完成后,直接呼叫该 Skill 的名称或使用
/db-design触发 - 根据 Skill 的参数说明提供必要输入,即可获得结构化输出
