For OHDSI network-study sites and OMOP data engineers
Your OMOP ETL, already run once.
Omopforge maps source tables to OMOP CDM 5.4, compiles the ETL SQL for SQLite, PostgreSQL, SQL Server and DuckDB, runs it on a synthetic sample and scores the result with the official OHDSI data-quality thresholds. You review a checked draft instead of writing SQL from a blank file.
Public Synthea sample, run 2026-11-14, 9.5 s, 0 model calls. Every number, its method and the one-command re-run.
Built to be checked
Mappings with reasons
Each source column and code lands on a CDM field or standard concept with the evidence for the pick, and unmapped items are listed, not guessed.
SQL that has run
The ETL is generated for four dialects and executed on your sample before you see it; the row counts reconcile block by block.
A scorecard to show
Data-quality results arrive in DQD's own JSON shape, so they open in the tools your network already uses.
