Define a New JDBC Connection to EDGAR Online Data

  1. If you have not already done so, install the Report Designer extension: Click File -> Install KNIME Extensions, and filter on "Report".
  2. In a new workflow, click File -> Preferences and expand the KNIME -> Database Driver nodes to add cdata.jdbc.edgaronline.jar. The driver JAR is located in the lib subfolder of the installation directory.
  3. In the Node Repository view, expand the Database node and drag a Database Reader onto the workflow editor.
  4. Double-click the Database Reader and set the following properties:

    • Database Driver: In the menu, select the CData JDBC driver.
    • Database URL: Enter the connection properties. The JDBC URL begins with jdbc:edgaronline: and is followed by a semicolon-separated list of connection properties.

      1. Navigate to https://developer.edgar-online.com/ and create an account.
      2. Register a new application and retrieve the AppKey. You should select one of the available Web APIs this application will use like HackPack, Insider Trades or Institutional Ownership.
        Note: HackPack is the most important Web API that an application can use since it supports a large number of endpoints. If you are getting the "Access Denied" error you must create a new app and select the correct Web API which supports the resource you are querying.
      3. After successfully creating a new app, you can access your keys through your "my account" area. Set the AppKey connection property value equal to the Key of your application.

      A typical JDBC URL is below. jdbc:edgaronline:AppKey=20dd8ce9904d422ed89ebde1ad40d

    • User Name: The username used to authenticate.
    • Password: The password used to authenticate.
    • SQL Statement: Enter an SQL query in the SQL Statement box or double-click a table. This article uses the query below to create a chart: SELECT Id, Name FROM Subscriptions WHERE SubscriberEmail = 'user@domain.com'
  5. Test the connection by clicking Fetch Metadata.

  6. Connect the Database Reader to a Data to Report node to supply the dataset to a range of data visualization controls. Click Execute and then click Edit Report at the top of the workflow to open the report designer perspective.
  7. You can now generate reports based on live data. To create a chart, drag the chart control from the palette to the report designer. In the resulting wizard, you can use the filtering and aggregation controls available in KNIME.
