Governed Migration, Lineage, and Catalog Reconciliation

How Theom supplies the evidence layer that keeps a modernizing enterprise data platform governed and its catalog accurate.

Executive perspective

Enterprises modernizing a data platform have to keep a large downstream analytics community running while the ground moves underneath it. The estate typically spans relational and microservice transactional sources, change-data capture and continuous-load ingestion staged through object storage, transformation and orchestration tooling on top, and a cloud warehouse or lakehouse on a medallion pattern serving BI, analytics teams, and a growing population of AI agents.

Theom provides the continuous evidence layer for that transition: what data exists, which data is sensitive, where it came from, who still uses raw or transitional paths, whether each identity’s access remains appropriate, how identity carries through BI and agent workflows, and where live platform evidence no longer matches the enterprise catalog.

Recommended starting point

Establish governance and migration evidence in the warehouse serving environment first, then extend the lineage graph across the lake and the upstream ingest and orchestration layers using the available connector and pipeline metadata.
