Common-Data-Model / PostgreSQL

This folder contains the SQL scripts for PostgreSQL.

In order to create your instantiation of the Common Data Model, we recommend following these steps:

Create an empty schema.
Execute the script OMOP CDM ddl - PostgreSQL.sql to create the tables and fields.
Load your data into the schema.
Execute the script OMOP CDM constraints - PostgreSQL.sql to add the constraints (primary and foreign keys).
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.
