CData Connect



Use the CData Connect Cloud to create an OData API for HPCC Systems data and build apps from live HPCC Systems 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 Connect Cloud creates a virtual database for HPCC Systems and can be used to generate an OData API (natively consumable in Qlik Sense Cloud) for HPCC Systems. By pairing Qlik Sense Cloud with the CData Connect Cloud, 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 Connect Cloud from Qlik Sense Cloud as you would any other REST service and get instant, live access to your HPCC Systems data.

In this article, we walk through two connections:

  1. Connecting to HPCC Systems in Connect Cloud
  2. Connecting to Connect Cloud from Qlik Sense Cloud to create a model and build a simple dashboard

Configure Connect Cloud to Connect to HPCC Systems

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

Add a Connect Cloud User

Create a Cloub Hub User to connect to HPCC Systems 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 HPCC Systems from Connect Cloud

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

  1. Open Connect Cloud and click Databases
  2. Select "HPCC Systems" from Available Data Sources
  3. Enter the necessary authentication properties to connect to HPCC Systems.

    To connect, set the following connection properties: Set URL to the machine name or IP address of the server and the port the server is running on, for example, https://server:port. The User and Password are required to authenticate to the HPCC Systems cluster specified in the URL. Note that LDAP authentication is not currently supported by our ODBC driver.

    Set Version to the WsSQL Web server version. Note that if you have not already done so, you will need to install the WsSQL service on the HPCC Systems server. The WsSQL Web service is used to interact with the underlying HPCC Systems platform.

    Set Cluster to the target cluster.

  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 HPCC Systems OData Endpoints in Connect Cloud

After connecting to HPCC Systems, create OData Endpoint for the desired table(s).

  1. Click OData -> Tables -> Add Tables
  2. Select the HPCC Systems 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 HPCC Systems Data

With the connection to HPCC Systems and OData endpoints created, we are ready to add HPCC Systems 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 HPCC Systems table, using the @CSV URL parameter to ensure a CSV response (i.e. https://www.cdatacloud.net/api.rsc/MYINSTANCE/HPCC_hpcc::test::orders?@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 Connect Cloud for the HPCC Systems 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 HPCC Systems data.
