Visualize MarkLogic Data in Tableau Desktop (through CData Connect)

Tableau is a visual analytics platform transforming the way businesses use data to solve problems. When paired with CData Connect (or Connect Server), you can easily get access to live MarkLogic data within Tableau.

CData Connect Server provides a pure SQL Server interface for MarkLogic, allowing you to easily build reports from live MarkLogic data in Tableau Desktop — without replicating the data to a natively supported database. As you build visualizations, Tableau Desktop 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 MarkLogic, leveraging server-side processing to quickly return the requested MarkLogic data.

This article shows how to create a virtual SQL Server database for MarkLogic, connect to the virtual database in Tableau, and build a simple chart.

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

   Set User, Password, and Server to the credentials for the MarkLogic account and the address of the server you want to connect to. You should also specify the REST API Port if you want to use a specific instance of a REST Server.

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 connect to MarkLogic data from Tableau Desktop.

Visualize Live MarkLogic Data in Tableau Desktop

The steps below outline connecting to the virtual MarkLogic database in CData Connect and building a simple visualization from the data.

1. Open Tableau and click "Microsoft SQL Server" under Connect -> To a Server.
2. In the connection wizard, enter the values for your CData Connect instance and click "Sign In"
   • Server: the address of your Connect instance and port of the TDS endpoint, separated by a comma (default port is: 1433)
   • Database: the virtual database you configured for the MarkLogic data
   • Username & Password: the credentials for a CData Connect user
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 MarkLogic Data from On-Premise Applications

At this point, you have a direct connection to live MarkLogic data from your Tableau Desktop workbook. You can create new visualizations, build dashboards, and more.
