This switch radically changes the assumptions related to exposure and outcome timing.

+This article was written to provide guidance on the setting of indices, primary and foreign keys for data that has been transformed into the Observational Medical Outcome Partnership (OMOP) Common Data Model (CDM).  The community that supports the design and development of the OHDSI/CommonDataModel Github repository is a diverse collaborative of healthcare and technical profesisonals whom have limited data base administrative (DBA) experience.  As a result, the comments below should be interpreted as suggestions and recommendations to help increase performance.  Your teams needs may call for a modified configuration.

 ### Visit Concept Roll-up
 
-The query below will utilize the Visit Concept hierarcy to find the highest-level ancestors. In the case that both the VISIT_OCCURRENCE and VISIT_DETAIL tables are populated, it is good practice (though not required) to use the highest-level ancestors as the VISIT_CONCEPT_IDs in the VISIT_OCCURRENCE table and their children as the VISIT_DETAIL_CONCEPT_IDs in the VISIT_DETAIL table. This relationship between the VISIT_OCCURRENCE and VISIT_DETAIL tables allow for standardized Visit logic to be written, building Visits from Visit Details. For more information on how this can be done, please see the [Optum Extended ETL documentation](https://ohdsi.github.io/ETL-LambdaBuilder/Optum%20Clinformatics/Optum_visit_occurrence.html).
