Top use cases
Save the prompts you reuse and regenerate diagrams every time your stack changes.
Document lakehouse or warehouse topologies with zones and contracts
Map lineage from source to BI with freshness and ownership
Produce architecture one-pagers for stakeholders and auditors
Standardize diagrams across teams with reusable prompt blocks
Workflow that ships
List domains (ingestion, processing, storage, serving) and key tools. Include SLAs per domain.
Add governance layers: catalogs, quality monitors, observability. Ask AI to color-code risk and PII zones.
Request lineage overlays showing upstream/downstream impact for critical metrics.
Publish and link the diagram to runbooks and data contracts for traceability.
Prompt recipes
Copy, tweak, and save in your repo so regenerations stay consistent.
"Draw a lakehouse with Bronze/Silver/Gold, ingestion via Airbyte, processing via dbt + Spark, catalog via Unity, and BI via Looker. Add freshness and owners."
"Show lineage for revenue metrics from Salesforce to staging to dbt models to semantic layer to dashboards. Include quality checks and SLAs."
"Create a modular data mesh view with domains, product owners, and contract boundaries. Highlight cross-domain pipelines."
Quality checklist
Bronze/Silver/Gold or staging/curated layers labeled with SLAs.
Each domain lists owner, contact channel, and data product definition.
Lineage nodes link to tests, contracts, and dashboards.
PII zones and access controls are visible for audits.
Why use Datadef
Prompt-to-canvas in seconds
Generate React Flow diagrams from prompts, then tweak nodes, metadata, and z-index with live collaboration.
Always in sync
Save prompts alongside canvas versions so you can regenerate diagrams as schemas, services, or policies change.
Shareable and auditable
Export PNG/SVG for decks, or share live canvases with lineage, SLAs, and runbook links for reviewers.
Built for data teams
Support data mesh, lakehouse, and streaming patterns with typed nodes for tables, pipelines, services, and governance layers.

FAQ
What makes a data architecture diagram useful for reviews?
It shows owners, SLAs, and edge contracts, not just boxes and arrows. Reviewers can see who is accountable and how data moves.
How do I represent quality checks?
Add edge labels for validations and use icons for schema checks, anomaly detection, and contract enforcement.
Can I track changes over versions?
Store prompts with git-friendly JSON. Regenerate diagrams after changes and keep published snapshots for auditors.
Ship faster
Generate your next diagram with AI
Capture the prompt once, regenerate after every schema change, and keep diagrams audit-ready.
