Database design principles and decision-making. Schema design, indexing strategy, ORM selection, serverless databases.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Database Design > **Learn to THINK, not copy SQL patterns.** ## Plan first A schema or service move starts from the `migration` template — safe cutover and a way back: ```bash aos-plan-canvas new migration <plan-dir> # scaffold the plan folder aos-plan-canvas open <plan-dir> --mode bdb-plan-builder # render and open in the browser aos-plan-canvas await <plan-dir>/plan.mdx # keep listening until the verdict ``` On `approve`, `aos-plan-canvas trail <plan-dir>` derives the agenttrail map. The full loop: the `plan-canvas` skill — a plain CLI, identical on every harness. ## 🎯 Selective Reading Rule **Read ONLY files relevant to the request!** Check the content map, find what you need. | File | Description | When to Read | |------|-------------|--------------| | `database-selection.md` | PostgreSQL vs Neon vs Turso vs SQLite | Choosing database | | `orm-selection.md` | Drizzle vs Prisma vs Kysely | Choosing ORM | | `schema-design.md` | Normalization, PKs, relationships | Designing schema | | `indexing.md` | Index types, composite indexes | Performance tuning | | `optimization.md` | N+1, EXPLAIN ANALYZE | Query optimization | …

How to install
mdr add hybridlabor-api/bdb-dev-optimized-agent-skills/database-design@sha256:8f8adef07037b10aThe line at the top of this page pins the label git:20261020.bfd01fa, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
