Visualize Azure Synapse Data in TIBCO Spotfire through OData

OData is a major protocol enabling real-time communication among cloud-based, mobile, and other online applications. The CData Connect Server provides Azure Synapse data to OData consumers like TIBCO Spotfire. This article shows how to use the Connect Server and Spotfire's built-in support for OData to access Azure Synapse data in real time.

Configuring Connect Server

To work with live Azure Synapse data in TIBCO Spotfire, we need to connect to Azure Synapse from Connect Server, provide user access to the new virtual database, and create OData endpoints for the Azure Synapse data.

Add a Connect Server User

Create a User to connect to Azure Synapse from TIBCO Spotfire through Connect Server.

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 Synapse from Connect Server

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

1. Open Connect Server and click Connections
2. Select "Azure Synapse" from Available Data Sources
3. Enter the necessary authentication properties to connect to Azure Synapse.

   Connecting to Azure Synapse

   In addition to providing authentication (see below), set the following properties to connect to a Azure Synapse database:

   • Server: The server running Azure. You can find this by logging into the Azure portal and navigating to Azure Synapse Analytics -> Select your database -> Overview -> Server name.
   • Database: The name of the database, as seen in the Azure portal on the Azure Synapse Analytics page.

   Authenticating to Azure Synapse

   Connect to Azure Synapse using the following properties:

   • User: The username provided for authentication with Azure.
   • Password: The password associated with the authenticating user.
4. Click Save Changes
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 Synapse OData Endpoints in Connect Server

After connecting to Azure Synapse, create OData Endpoints for the desired table(s).

1. Click OData -> Tables -> Add Tables
2. Select the Azure Synapse 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 Data Visualizations on External Azure Synapse Data

1. Open Spotfire and click Data -> Add data...
2. Then, click "Connect to" -> OData -> New Connection. In the OData Connection dialog, enter the following information:
   • Service URL: Enter the Connect Server's OData endpoint. For example: http://localhost:8080/odata.rsc
   • Authentication Method: Select Username and Password.
   • Username: Enter the username of a Connect Server user. You can create API users on the Security tab of the administration console.
   • Password: Enter the authtoken of a Connect Server user.
3. Select the tables and columns you want to add to the dashboard. This example uses Products.

4. If you want to work with the live data, click the Keep Data Table External option. This option enables your dashboards to reflect changes to the data in real time.

   If you want to load the data into memory and process the data locally, click the Import Data Table option. This option is better for offline use or if a slow network connection is making your dashboard less interactive.

5. After you have selected a table, Spotfire uses the data to detect number, time, and other categories. You are now on your way to creating new visualizations for analytics, reporting, and more.
