Import Data Modeling assets into Atlan
🎉 What’s new
Atlan now enables cataloging of Entity–Relationship (ER) models, helping teams bridge the gap between business and technical users. With ER model metadata in Atlan, organizations can enhance collaboration, streamline change management, and reinforce data governance.
✨ Let’s dig deeper
Ingest ER models with ease
You can now bring your ER models into Atlan using an Excel template:
- Data model ingestion – Use Atlan’s custom package to ingest ER models via an Excel template.
Unlock new capabilities with ER models
- Foster collaboration – Business and technical users can now share a unified view of data relationships across systems, breaking down silos.
- Simplify impact analysis – Visualizing entity relationships helps assess the downstream impact of technical changes with confidence.
- Strengthen governance – Define access controls, retention policies, and governance rules based on entity relationships, ensuring trust and accountability.
Visualize and map your data
- Entity Diagrams – Navigate entities, attributes, and relationships visually to simplify understanding and communication.
- Conceptual, Logical, and Physical Models – Map ER models across different abstraction levels to align business concepts with technical implementation.
- Link ER Entities to crawled assets – Link entities to actual data assets in Atlan (e.g., an ‘Order’ table in Snowflake).
