Design system data flows and data-layer ownership, consistency, and store choices from access patterns. Use for critical-flow design, DFD semantic review, data lineage, authority, replication, retention, or a data-tier bottleneck. Avoid unrelated framework stream/dataframe implementation questions.
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
# Data Architecture ## **Priority: P1 (HIGH)** Access patterns and per-operation invariants choose the store. Ownership precedes schema. Shard last, not first. Trace critical flows before committing to stores or transport; diagrams are conditional. ## Store Selection 1. List every read and write access pattern with its QPS, latency target, and consistency need. 2. Default to a relational store. It wins until a specific pattern proves it cannot serve. 3. Move a pattern to a specialized store only when the relational store fails that named pattern: key-value for hot lookups, wide-column for massive ordered writes, document for schema-variant aggregates, graph for multi-hop traversal, search index for text and facets, object store for blobs. 4. Every additional store adds sync lag, dual-write risk, and one more operational surface. Justify it. 5. Blobs never live in the primary database; store bytes in object storage and keep the reference. ## Ownership and Consistency …

How to install
mdr add hoangnguyen0403/agent-skills-standard/system-design-data-architecture@sha256:e673583ba86f4fb9The line at the top of this page pins the label git:20261027.4acc21f, 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.
