Create Apps from Azure Data Catalog Data in Qlik Sense Cloud

Use the CData Cloud Hub to create an OData API for Azure Data Catalog data and build apps from live Azure Data Catalog data in Qlik Sense Cloud.

Qlik Sense Cloud allows you to create and share data visualizations and interact with information in new ways. The CData Cloud Hub creates a virtual database for Azure Data Catalog and can be used to generate an OData API (natively consumable in Qlik Sense Cloud) for Azure Data Catalog. By pairing Qlik Sense Cloud with the CData Cloud Hub, you get true cloud-to-cloud connectivity to all of your SaaS and cloud-based Big Data and NoSQL sources — no need to migrate your data or write your integrations. Simply connect to the Cloud Hub from Qlik Sense Cloud as you would any other REST service and get instant, live access to your Azure Data Catalog data.

In this article, we walk through two connections:

  1. Connecting to Azure Data Catalog in the Cloud Hub
  2. Connecting to the Cloud Hub from Qlik Sense Cloud to create a model and build a simple dashboard

Configure Cloud Hub to Connect to Azure Data Catalog

To connect to Azure Data Catalog data from Qlik Sense Cloud, you need to configure Azure Data Catalog access from your Cloud Hub instance. This means creating a user, connecting to Azure Data Catalog, adding OData endpoints, and (optionally) configuring CORS.

Add a Cloud Hub User

Create a Cloub Hub User to connect to Azure Data Catalog from Qlik Sense Cloud.

  1. Click Users -> Add
  2. Configure a User
  3. Click Save Changes and make note of the Authtoken for the new user

Connect to Azure Data Catalog from Cloud Hub

CData Cloud Hub uses a straightforward, point-and-click interface to connect to data sources and generate APIs.

  1. Open Cloud Hub and click Databases
  2. Select "Azure Data Catalog" from Available Data Sources
  3. Enter the necessary authentication properties to connect to Azure Data Catalog.

    You can optionally set the following to read the different catalog data returned from Azure Data Catalog.

      CatalogName: Set this to the CatalogName associated with your Azure Data Catalog. To get your Catalog name, navigate to your Azure Portal home page > Data Catalog > Catalog Name

    Connect Using OAuth Authentication

    You must use OAuth to authenticate with Azure Data Catalog. OAuth requires the authenticating user to interact with Azure Data Catalog using the browser. For more information, refer to the OAuth section in the help documentation.

  4. Click Test Database
  5. Click Privileges -> Add, and add the new user (or an existing user) with the appropriate permissions (SELECT is all that is required for Reveal)

Add Azure Data Catalog OData Endpoints in Cloud Hub

After connecting to Azure Data Catalog, create OData Endpoint for the desired table(s).

  1. Click OData -> Tables -> Add Tables
  2. Select the Azure Data Catalog database
  3. Select the table(s) you wish to work with and click Next
  4. (Optional) Edit the resource to select specific fields and more
  5. Save the settings

(Optional) Configure Cross-Origin Resource Sharing (CORS)

When accessing and connecting to multiple domains from an application such as Ajax, there is a possibility of violating the limitations of cross-site scripting. In that case, configure the CORS settings in OData -> Settings.

  • Enable cross-origin resource sharing (CORS): ON
  • Allow all domains without '*': ON
  • Access-Control-Allow-Methods: GET, PUT, POST, OPTIONS
  • Access-Control-Allow-Headers: Authorization

Save the changes to the settings.

Create a Qlik Sense App from Azure Data Catalog Data

With the connection to Azure Data Catalog and OData endpoints created, we are ready to add Azure Data Catalog data to a Qlik Sense app for visualizations, analytics, reporting, and more.

Create a New App and Upload Data

  1. Log into your Qlik Sense instance and click the button to create a new app
  2. Name and configure the new app and click "Create"
  3. In the workspace, click to open the new app
  4. Click to add data from files and other sources
  5. Select the REST connector and set the configuration properties. For the most part, you will use the default values, with the following exceptions:
    • URL: Set this to the API endpoint for your Azure Data Catalog table, using the @CSV URL parameter to ensure a CSV response (i.e. https://www.cdatacloud.net/api.rsc/MYINSTANCE/AzureDataCatalog_Tables?@CSV)
    • Authentication Schema: Set this to "Basic"
    • User Name: Set this to the user name you configured above
    • Password: Set this to the Authtoken for the above user
  6. Click "Create" to query the Cloud Hub for the Azure Data Catalog data
  7. Check "CSV has header" and under "Tables," select "CSV_source"
  8. Select columns and click "Add data"

Generate Insights or Customize Your App

With the data loaded into Qlik Sense, you are ready to begin discovering insights. Click "Generate insights" to let Qlik analyze your data. Otherwise, you can build custom visualizations, reports, and dashboards based on your Azure Data Catalog data.
