Connect to FHIR Data in RazorSQL

The CData JDBC Driver for FHIR enables standards-based access from third-party tools, from wizards in IDEs to data management and analysis tools. This article shows how to connect to FHIR using wizards in RazorSQL.

Create a JDBC Data Source for FHIR Data

1. Open the RazorSQL application and, in the Connections menu, select Add Connection Profile -> Other -> JDBC.
2. In the Connection Wizard that appears, set the following properties:
   • Driver Location: Set this property to the path to the lib subfolder in the installation directory.
   • Driver Class: Set the driver class to cdata.jdbc.fhir.FHIRDriver.
   • Username: Enter the username. (This property can also be set in the JDBC URL.)
   • Password: Enter the password. (This property can also be set in the JDBC URL.)

   • JDBC URL: Enter connection parameters. The JDBC URL begins with jdbc:fhir: and is followed by a semicolon-separated list of connection properties.

     Set URL to the Service Base URL of the FHIR server. This is the address where the resources are defined in the FHIR server you would like to connect to. Set ConnectionType to a supported connection type. Set ContentType to the format of your documents. Set AuthScheme based on the authentication requirements for your FHIR server.

     Generic, Azure-based, AWS-based, and Google-based FHIR server implementations are supported.

     Sample Service Base URLs

     • Generic: http://my_fhir_server/r4b/
     • Azure: https://MY_AZURE_FHIR.azurehealthcareapis.com/
     • AWS: https://healthlake.REGION.amazonaws.com/datastore/DATASTORE_ID/r4/
     • Google: https://healthcare.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/datasets/DATASET_ID/fhirStores/FHIR_STORE_ID/fhir/

     Generic FHIR Instances

     The product supports connections to custom instances of FHIR. Authentication to custom FHIR servers is handled via OAuth (read more about OAuth in the Help documentation. Before you can connect to custom FHIR instances, you must set ConnectionType to Generic.

     Built-in Connection String Designer

     For assistance in constructing the JDBC URL, use the connection string designer built into the FHIR JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

     java -jar cdata.jdbc.fhir.jar

     Fill in the connection properties and copy the connection string to the clipboard.

     A typical JDBC URL is the following:

     jdbc:fhir:URL=http://test.fhir.org/r4b/;ConnectionType=Generic;ContentType=JSON;AuthScheme=None;

Query FHIR Data and Select Tables

After establishing a connection, the wizard will close and the connection will be available in the connections panel. You can then query the tables.
