Databricks provides a JDBC driver to connect your applications or tools to Databricks clusters using Java Database Connectivity (JDBC), an industry standard.

Key steps to establish a Databricks JDBC connection:

1. Download the JDBC driver: Get the Databricks JDBC driver from the official documentation.
2. Gather connection details: Obtain the server hostname, HTTP path, personal access token, or other authentication credentials.
3. Construct the JDBC URL: Formulate the JDBC URL, incorporating the server hostname, HTTP path, and authentication settings.
4. Establish the connection: Use the JDBC URL and driver to initiate a connection to your Databricks cluster.

Example JDBC URL (using personal access token):

JDBC:databricks://<server-hostname>:443;transportMode=http;httpPath=<http-path>;AuthMech=3;UID=token;PWD=<personal-access-token>
