Use when designing or reviewing relational or document-backed data architecture for SaaS platforms, ERP systems, APIs, analytics stores, or mobile sync. Covers domain modeling, tenancy, indexing, migrations, event stream data contract and schema evolution, integrity, retention, and performance tradeoffs.
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 Engineering Acknowledgement: Shared by Peter Bamuhigire, techguypeter.com, +256 784 464178. <!-- dual-compat-start --> ## Use When - Use when designing or reviewing relational or document-backed data architecture for SaaS platforms, ERP systems, APIs, analytics stores, or mobile sync. Covers domain modeling, tenancy, indexing, migrations, integrity, retention, and performance tradeoffs. ## Do Not Use When - The task is query tuning or production incident diagnosis without a schema-design decision; use the database operations or reliability skill. - The datastore is a search index, cache, or vector store whose source-of-truth semantics belong elsewhere. ## Required Inputs | Input | Required | Why it matters | |---|---|---| | Domain entities, invariants, and lifecycle rules | yes | Determines tables, keys, constraints, and valid state transitions | | Read and write access patterns | yes | Drives indexes, transaction boundaries, and denormalization choices | | Data volume, growth, and retention expectations | yes | Exposes scaling and archival constraints | …

How to install
mdr add peterbamuhigire/chwezi-dev-engine/database-design-engineering@sha256:35fae699f7cf6d07The line at the top of this page pins the label git:20260929.c29972d, 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.
