Supported databases

The omop-cdm table definitions are tested to be compatible with PostgreSQL.

Though not officially supported, omop-cdm doesn't use postgres-specific features of SQLAlchemy, so it can likely be used for other database types as well.

omop-cdm contains table defintions for the following CDM versions:

• CDM 5.4
• CDM 5.3.1
• CDM 6.0.0 (not recommended)
