DbSchema Snowflake ER Diagram Designer

DbSchema is a Snowflake ER diagram database designer and query tool. Using DbSchema, you can design and document Snowflake databases while connected to the database server or without a connection.

Next, you can share the design with the team using Git. The design model loaded in DbSchema can be compared with the database, synchronization scripts can be generated, and the schema can be deployed to any database server.

How to Connect to a Snowflake Database

Watch the step-by-step video tutorial below:

For written documentation, please continue reading...

Open DbSchema, then click "Connect to Database" on the Main Screen and choose your database system. DbSchema will automatically download the required JDBC driver.

Standard Connection Setup

Configure the Remote Connection in DbSchema

In DbSchema's connection dialog, you can choose "Standard" for a simplified setup, or "Edit Manually" to customize the JDBC URL.

Step 1: Obtain Your Account URL

To connect DbSchema to your Snowflake database, begin by obtaining your account URL from the Snowflake Console , as shown below

Account URL from Snowflake Console

Step 2: Configure the Connection in DbSchema

Option 1: Standard Connection

If you choose the "Standard" connection option:

  • Copy your account URL from the Snowflake Console (e.g., https://xx32991.europe-west3.gcp.snowflakecomputing.com .
  • Paste the URL into the "Server Host or IP" field in DbSchema, but remove the "https://" prefix.
  • Enter your Snowflake username and password, then click "Connect."
    • Standard Connection Setup

  • Once connected, DbSchema will reverse-engineer your database schema, creating a visual layout of your tables and relationships.

Option 2: Edit Manually

  • If you select "Edit Manually," enter the JDBC URL using this format:

    • jdbc:snowflake:// your_account_URL ?client_metadata_request_use_connection_ctx=true

  • Replace your_account_URL with your Snowflake account URL. Next, enter your Snowflake username and password, and click "Connect."
  • Once connected, DbSchema will reverse-engineer your database schema, creating a visual layout of your tables and relationships.

Troubleshoot Firewall Issues

If you experience connection problems, check your firewall and antivirus settings, as they might be blocking the connection. More information on enabling Firewall Connections is available if needed.

Enable Windows Firewalls Note: Firewalls and antivirus software may block database connections.
