Use CData Connect Server to create a virtual SQL Server Database for HarperDB 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 HarperDB data for visualizations, dashboards, and more. This article shows how to create a virtual database for HarperDB and build visualizations from HarperDB data in Tableau Cloud.
CData Connect Server provides a pure SQL Server interface for HarperDB, allowing you to easily build visualizations from live HarperDB 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 HarperDB, leveraging server-side processing to quickly return HarperDB data.
Create a Virtual SQL Server Database for HarperDB Data
CData Connect Server uses a straightforward, point-and-click interface to connect to data sources and generate APIs.
- Login to Connect Server and click Connections.
- Select "HarperDB" from Available Data Sources.
-
Enter the necessary authentication properties to connect to HarperDB.
Set the Server, User, and Password connection properties to connect to HarperDB. Set UseSSL to secure connections with TLS/SSL.
- Click Save Changes
- 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 HarperDB Data in Tableau Cloud
The steps below outline creating a new data source in Tableau Cloud based on the virtual HarperDB database in Connect Server and building a simple visualization from the data.
- Log into Tableau Cloud, select a project, and create a new workbook.
- 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. - Select your newly created database and the table(s) you wish to visualize (defining relationships for JOINed tables as needed).
- Select Dimensions and Measures and configure your visualization.
SQL Access to HarperDB Data from Applications
At this point, you have a direct connection to live HarperDB 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.
