![]() ![]() Teams and organisations Toggle sub-navigation.Now, you can create a horizontal bar chart displaying this data, and even use Tableau online to host this data for sharing and presentation purposes. Provide a count on the total customers and transactions.In our instance, we can use the Measure Names calculation in the columns field, and the Measure Values calculation in the rows, which will: We can drag and drop these collections and link them together like so.Īs we have created relationships between the customers to transactions as well as Accounts1, we can now go to our worksheet Sheet1 to start creating tables to view our data. Let’s begin in the “Data Source” homepage of Tableau.įor example, in the sample_analytics database, we’ve got various collections including customers and transactions. Tableau table with information about students and gradesĪfter Tableau has been connected to our Atlas cluster, we are able to see all of our collections from the federated database, and start working with our data to create visualizations. Now, you’ll have an output from Tableau that we can begin to start analyzing and creating visualizations from to make better data-driven decisions. Tableau prompt for selecting schema levels moving forward after json import Once opened, you can specify the required schema levels to include for analysis. Now, with our exported JSON file ready, we can open Tableau’s JSON connector and select our file. Template commands for mongoimport and mongoexportįor example, if we wanted to export the transactions collection in our sample_analytics MongoDB database to a file called export.json mongoexport -uri -collection transactions -out export.json On the “Data Import and Export Tools” section, we can find a template command to produce an export of data stored in a MongoDB instance that we can then analyze using Tableau. Navigating to the Command Line Tools page To easily use mongoexport and generate a JSON file, we can use the “Command Line Tools” tab of our “Database Deployments” page. This can be done using mongoexport, a CLI-tool that produces a JSON or CSV export of data stored in a MongoDB instance. In that case, use Tableau’s JSON connector to understand the data without any data preparation. Perhaps we’d like to export our MongoDB data in order to analyze and make insightful decisions. Tableau dashboard after connecting via Atlas SQL Interface If the connection was successful, you should see your database and collections that exist as part of your federated database instance within Tableau. ![]() When prompted, enter the URI, database, username, and password information associated with the federated database instance within MongoDB Atlas.Įntering the necessary credentials to access the database via Tableau Choose "MongoDB Atlas by MongoDB" as your MongoDB Tableau connector option. Open Tableau Desktop or Tableau Server and navigate to the "Connect" menu. Selecting the URI to connect via the Tableau connector The database that you want to use as part of your connection is within "Configuration" section of your particular federated instance. Take note of the "URI" in the "Tableau Connector" tab, but not the "Database" field. For the instance you'd like to connect to, click the "Connect" button followed by "Connect using the Atlas SQL Interface" button.Ĭonnecting to Tableau using the Atlas SQL Interface Within MongoDB Atlas, click the "Data Federation" tab. We need to obtain the connection information for that instance to be used in Tableau. You should already have a federated database instance within MongoDB as per the requirements of this tutorial. Once again, if the directory doesn't exist, go ahead and create it. Windows: C:\Program Files\Tableau\Connectors.You'll want to move this file to one of two places depending on your operating system: Next, download the Tableau Named Connector, also known as a TACO file. The directory should exist, but if it doesn't, go ahead and create it. Windows: C:\Program Files\Tableau\Drivers.You'll need to move this downloaded file to one of two places depending on your operating system: To make use of the Tableau Named Connector, you'll need a few extra files to get Tableau recognizing the connection option.įirst, download the MongoDB JDBC Driver and make sure to choose the *.all.jar version from the list. Connect Tableau to MongoDB with the Tableau Named Connector
