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 Open Exchange Rates data for visualizations, dashboards, and more. This article shows how to create a virtual database for Open Exchange Rates and build visualizations from Open Exchange Rates data in Tableau Online.

CData Connect Cloud provides a pure SQL Server, cloud-to-cloud interface for Open Exchange Rates, allowing you to easily build visualizations from live Open Exchange Rates 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 Open Exchange Rates, leveraging server-side processing to quickly return Open Exchange Rates data.

Create a Virtual SQL Server Database for Open Exchange Rates 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 "Open Exchange Rates" from Available Data Sources.
