We are layered between the fact table (built during ETL) and the CRC (Clinical Research Chart) data mart which i2b2 uses … grant is approved. 2) Our system reads data from the Observable Fact Table and writes data to a new fact table called the Map Data Fact Table.

The legacy i2b2 data model is comprised of a central fact table (observation_fact) surrounded by multiple dimension tables (star schema). In the Observation Medical Outcomes Partnership (OMOP) Clinical Data Model (CDM) rather than a central fact table, we have a collection of them distinguished by domain: proceduresTranslational Bioinformatics Warehouse Database Design v3.doc

warehouse modeled on the star schema structure first proposed by Ralph Kimball. The database schema looks like a star, with one central fact table surrounded radially by one or more dimension tables. The most important concept regarding the construction of a star schema is identifying what constitutes a fact711. Background
