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

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

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

Create a Virtual SQL Server Database for HPCC Systems Data

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

  1. Login to Connect Cloud and click Databases.
  2. Select "HPCC Systems" from Available Data Sources.
  3. Enter the necessary authentication properties to connect to HPCC Systems.

    To connect, set the following connection properties: Set URL to the machine name or IP address of the server and the port the server is running on, for example, https://server:port. The User and Password are required to authenticate to the HPCC Systems cluster specified in the URL. Note that LDAP authentication is not currently supported by our ODBC driver.

    Set Version to the WsSQL Web server version. Note that if you have not already done so, you will need to install the WsSQL service on the HPCC Systems server. The WsSQL Web service is used to interact with the underlying HPCC Systems platform.

    Set Cluster to the target cluster.

  4. Click Test Database.
  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 Online.

Visualize Live HPCC Systems Data in Tableau Online

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

  1. Log into Tableau Online, 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 Cloud 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 HPCC Systems Data from Cloud Applications

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