Build FTP 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 FTP data for visualizations, dashboards, and more. This article shows how to create a virtual database for FTP and build visualizations from FTP data in Tableau Cloud.

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

Create a Virtual SQL Server Database for FTP 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 "FTP" from Available Data Sources.
3. Enter the necessary authentication properties to connect to FTP.

   To connect to FTP or SFTP servers, specify at least RemoteHost and FileProtocol. Specify the port with RemotePort.

   Set User and Password to perform Basic authentication. Set SSHAuthMode to use SSH authentication. See the Getting Started section of the data provider help documentation for more information on authenticating via SSH.

   Set SSLMode and SSLServerCert to secure connections with SSL.

   The data provider lists the tables based on the available folders in your FTP server. Set the following connection properties to control the relational view of the file system:

   • RemotePath: Set this to the current working directory.
   • TableDepth: Set this to control the depth of folders to list as views.
   • FileRetrievalDepth: Set this to retrieve and list files recursively from the root table.

   Stored Procedures are available to download files, upload files, and send protocol commands. See the Data Model chapter of the FTP data provider documentation for more information.

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 FTP Data in Tableau Cloud

The steps below outline creating a new data source in Tableau Cloud based on the virtual FTP 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 FTP Data from Applications

At this point, you have a direct connection to live FTP 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.
