Build DB2 Visualizations in Tableau Cloud



Use CData Connect Server to create a virtual SQL Server Database for DB2 data and build visualizations in Tableau Cloud.

Tableau Cloud is an analytics platform fully hosted in the cloud. When paired with CData Connect Server, you get instant, cloud-to-cloud access to DB2 data for visualizations, dashboards, and more. This article shows how to create a virtual database for DB2 and build visualizations from DB2 data in Tableau Cloud.

CData Connect Server provides a pure SQL Server interface for DB2, allowing you to easily build visualizations from live DB2 data in Tableau Cloud without installing connectors or publishing worksheets and data sources from Tableau Desktop. As you build visualizations, Tableau Cloud generates SQL queries to gather data. Using optimized data processing out of the box, CData Connect Server pushes all supported SQL operations (filters, JOINs, etc) directly to DB2, leveraging server-side processing to quickly return DB2 data.

Create a Virtual SQL Server Database for DB2 Data

CData Connect Server uses a straightforward, point-and-click interface to connect to data sources and generate APIs.

  1. Login to Connect Server and click Connections.
  2. Select "DB2" from Available Data Sources.
  3. Enter the necessary authentication properties to connect to DB2.

    Set the following properties to connect to DB2:

    • Server: Set this to the name of the server running DB2.
    • Port: Set this to the port the DB2 server is listening on.
    • Database: Set this to the name of the DB2 database.
    • User: Set this to the username of a user allowed to access the database.
    • Password: Set this to the password of a user allowed to access the database.

    You will also need to install the corresponding DB2 driver:

    • Windows: Install the IBM Data Server Provider for .NET.

      On Windows, installing the IBM Data Server Provider is sufficient, as the installation registers it in the machine.config.

    • Java: Install the IBM Data Server Driver for JDBC.

      In the Java version, place the IBM Data Server Driver JAR in the www\WEB-INF\lib\ folder for this application.

  4. Click Save Changes
  5. Click Privileges -> Add and add the new user (or an existing user) with the appropriate permissions.

With the virtual database created, you are ready to build visualizations in Tableau Cloud.

Visualize Live DB2 Data in Tableau Cloud

The steps below outline creating a new data source in Tableau Cloud based on the virtual DB2 database in Connect Server and building a simple visualization from the data.

  1. Log into Tableau Cloud, select a project, and create a new workbook.
  2. In the new workbook, choose the Microsoft SQL Server Connector from the data wizard and fill in the values for your Connect Server instance.
    NOTE: Be sure to check the "Require SSL" checkbox.
  3. Select your newly created database and the table(s) you wish to visualize (defining relationships for JOINed tables as needed).
  4. Select Dimensions and Measures and configure your visualization.

SQL Access to DB2 Data from Applications

At this point, you have a direct connection to live DB2 data from your Tableau Cloud workbook. You can create new visualizations, build dashboards, and more, with no need to publish data sources and workbooks from Tableau Desktop.
