How to connect to FHIR Data in DBVisualizer

The CData JDBC Driver for FHIR implements JDBC standards to provide connectivity to FHIR data in applications ranging from business intelligence tools to IDEs. This article shows how to establish a connection to FHIR data in DBVisualizer and use the table editor to load FHIR data.

Create a New Driver Definition for FHIR Data

Follow the steps below to use the Driver Manager to provide connectivity to FHIR data from DBVisualizer tools.

1. In DBVisualizer, click Tools -> Driver Manager.
2. Click the plus sign "" to create a new driver.
3. Select "Custom" as the template.
4. On the Driver Settings tab:
   • Set Name to a user-friendly name (e.g. "CData FHIR Driver")
   • Set URL Format to jdbc:fhir: 👁 Setting the Driver Settings (Salesforce is shown).
     
   • In Driver artifacts and jar files (jars are loaded in order from top):
     1. Click the plus sign "" -> "Add Files"
     2. Navigate to the "lib" folder in the installation directory (C:\Program Files\CData JDBC Driver for FHIR XXXX\)
     3. Select the JAR file (cdata.jdbc.FHIR.jar) and click "Open"
     👁 Loading the driver JAR file.
     
5. The Driver Class should populate automatically. If not, select class (cdata.jdbc.fhir.FHIRDriver).

Define the Connection to the JDBC Data Source

Close the "Driver Manager" and follow the steps below to save connection properties in the JDBC URL.

1. In the "Databases" tab, click the plus sign "" and select the driver you just created.

2. In the "Connection" section, set the following options:

   • Database Type: If you selected the wizard option, the database type is automatically detected. If you selected the "No Wizard" option, select the Generic or Auto Detect option in the Database Type menu.
   • Driver Type: Select the driver you just created.

   • Database URL: Enter the full JDBC URL. The syntax of the JDBC URL is jdbc:fhir: followed by the connection properties in a semicolon-separated list of name-value pairs.

     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.

     When you configure the JDBC URL, you may also want to set the Max Rows connection property. This will limit the number of rows returned, which is especially helpful for improving performance when designing reports and visualizations.

     A typical connection string is below:

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

   • NOTE: Since FHIR does not require a User or Password to authenticate, you may use whatever values you wish for Database Userid and Database Password.
3. On the Connection tab, click Connect. 👁 A newly configured Database Connection. (Salesforce is shown.)
   

To browse through tables exposed by the FHIR JDBC Driver, right-click a table and click "Open in New Tab."

To execute SQL queries, use the SQL Commander tool: Click SQL Commander -> New SQL Commander. Select the Database Connection, Database, and Schema from the available menus.

See the "Supported SQL" chapter in the help documentation for more information on the supported SQL. See the "Data Model" chapter for table-specific information.
