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:
1. 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.
