Data Mapping

How source data flows from Epic and CDW into OMOP — the ELT pipeline, vocabulary mapping coverage, and custom concept extensions.

  • Extract Load Transform (ELT)


    The DBT-based pipeline that transforms raw clinical data from Epic and CDW into OMOP CDM tables, orchestrated by Apache Airflow on Amazon Redshift.

    ELT Pipeline

  • Vocabulary Mapping Coverage


    Live dashboard showing mapping progress across all CVB vocabulary projects — coverage percentages, predicate distributions, and top items by frequency.

    Mapping Coverage

  • Custom Concepts


    Emory-specific vocabulary extensions for data elements not covered by standard OHDSI ontologies. Request mappings or contribute vocabularies through the CVB pipeline.
