Polyglot persistence: when to use relational, graph or document databases; integration patterns.
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
# Polyglot Persistence Architecture Architectural guidance for using multiple database technologies together, with emphasis on PostgreSQL/Supabase (relational), Neo4j (graph), and MongoDB (document). Demonstrates when to use each database type and how to integrate them effectively. ## When This Skill Applies Use this skill when: - Designing data architecture for new projects - Choosing between relational, graph and document databases - Integrating multiple database types - Schema design decisions - Query optimisation across databases - Migration strategies - Questions about when to use which database paradigm ## Core Principle **Start with the graph. Optimise from there.** Most real-world domains are fundamentally about relationships. The graph is the truest representation of how entities connect. Start by thinking in nodes and edges, then decide where to persist based on access patterns and consistency needs. **Right database for right data concern** Don't force all data into one database type. Use: - **Relational (PostgreSQL/Supabase)** - Structured data, transactions, strong consistency - **Graph (Neo4j)** - Relationships as primary concern, traversal queries …

How to install
mdr add jasonwarrenuk/goblin-mode/Role: Data Ontologist@sha256:8ea185082594ef79The line at the top of this page pins the label git:20261008.c2dff9e, 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.
