The i2b2/tranSMART common data model is the primary patient data model used in i2b2 and tranSMART. It consists of a "star schema": one table for the multitude of patient-related observations, supported by "dimension" tables for patient demographics, encounter datarecords, provider datainformation, etc.

The OMOP common data model is used by many institutions for research. It can be used in the i2b2 CRC database for recording patient data. Many institutions prefer this format over the i2b2 CDM because it more readily supports research outside of i2b2. This CDM can also be joined with the i2b2 CDM to allow the patient data to remain in the OMOP CDM tables, while the i2b2 software accesses the patient data through database views.
