Create an empty schema. + +2. Execute the script `OMOP CDM ddl - PostgreSQL.sql` to create the tables and fields. + +3. Load your data into the schema. + +4. Execute the script `OMOP CDM constraints - PostgreSQL.sql` to add the constraints (primary and foreign keys). + +5. Execute the script `OMOP CDM indexes required - PostgreSQL.sql` to add the minimum set of indexes we recommend. + +Note: you could also apply the constraints and/or the indexes before loading the data, but this will slow down the insertion of the data considerably.
