Purpose: to provide an oncology-extension focused implementation of SQLAlchemy ORM definitions with opinionated enforcement of data conventions.
For reference, see background 2023 OHDSI APAC symposium paper.
If you don't want to install and configure a sagecipher keyring for credential management, you can instead create file pwd_override.txt under oa_config.app_root, containing just plaintext password, which will override the keyring functionality.
Create oa_system_config.yaml in this same directory to specify your local or system database parameters for connection. oa_system_config_demo.yaml has been provided as a template example.
