Top use cases
Save the prompts you reuse and regenerate diagrams every time your stack changes.
Document streaming via Pub/Sub and Dataflow with SLAs
Show BigQuery storage/compute separation and slot planning
Highlight governance: IAM, VPC-SC, and Data Catalog
Share reference architectures for teams migrating to GCP
Workflow that ships
List projects by domain and add ingestion patterns (Pub/Sub, Storage).
Add processing (Dataflow/Spark on Dataproc) and serving (BigQuery, Looker).
Ask AI to mark governance (IAM, VPC-SC) and data products.
Publish diagrams with cost levers (slots, reservations, storage classes).
Prompt recipes
Copy, tweak, and save in your repo so regenerations stay consistent.
"Draw a GCP data platform with Pub/Sub ingest, Dataflow streaming, BigQuery warehouse, and Looker. Add VPC-SC and IAM."
"Show hybrid batch + streaming for event analytics with Storage, Dataflow, BigQuery, and dbt. Include slots and reservations."
"Create a migration blueprint from on-prem to GCP with stages and cutover plan."
Quality checklist
Projects grouped by domain with clear ownership.
IAM roles and VPC-SC noted on sensitive data paths.
BigQuery slot plans and cost levers visible.
Streaming SLAs and backfill paths documented.
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
How do I show slot planning?
Add reservations and assignments per workload. AI can surface where isolation or autoscaling is needed.
What about VPC-SC?
Note service perimeters on data products that need egress control. Keep labels concise.
Can I cover Looker and BI?
Yes. Include semantic models and dashboards so consumers know where data is certified.
