Introduction

Eunomia is a standard dataset manager for sample OMOP (Observational Medical Outcomes Partnership) Common Data Model (CDM) datasets. Eunomia facilitates access to sample datasets from the EunomiaDatasets repository. Eunomia is used for testing and demonstration purposes, including many of the exercises in the Book of OHDSI. For functions that require schema name, use ‘main’.

Features

  • Download selected sample datasets from EunomiaDatasets repository, which includes a subset of the Standardized Vocabularies.
  • Interfaces with the DatabaseConnector and SqlRender packages.
  • No need to set up a database server. Eunomia runs in your R instance (currently using SQLite).
  • (planned) supports for other databases

Example 

library(Eunomia)
connectionDetails <- getEunomiaConnectionDetails()
connection <- connect(connectionDetails)
querySql(connection, "SELECT COUNT(*) FROM person;")
#  COUNT(*)
#1     2694

getTableNames(connection,databaseSchema = 'main')
disconnect(connection)
