Analyze Teradata Data in Infragistics Reveal

Reveal is a data visualization solution provided by Infragistics and can be paired with the CData Connect Server and Teradata Connector to build dynamic dashboards from live Teradata data. The CData Connect Server creates a virtual database for Teradata and can be used to generate an OData API (natively consumable in Reveal) for Teradata. In this article, we walk through connecting to Teradata in Connect Server and connecting to Connect Server from Infragistics Reveal to create a simple dashboard.

Add a Connect Server User

Create a User to connect to Teradata from Reveal 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 Teradata 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 "Teradata" from Available Data Sources
3. Enter the necessary authentication properties to connect to Teradata.

   To connect to Teradata, provide authentication information and specify the database server name.

   • User: Set this to the username of a Teradata user.
   • Password: Set this to the password of the Teradata user.
   • DataSource: Specify the Teradata server name, DBC Name, or TDPID.
   • Port: Specify the port the server is running on.
   • Database: Specify the database name. If not specified, the default database is used.
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 Teradata OData Endpoints in Connect Server

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

1. Click OData -> Tables -> Add Tables
2. Select the Teradata 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 different 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 Dashboard in Reveal

With Connect Server configured, we can visualize Teradata data in Reveal.

1. Log into Reveal and click Dashboards -> New
2. Click Data Source -> OData Feed
3. Specify the Connect Server API endpoint URL (found in API -> Discovery -> Base URL), for example: CONNECT_SERVER_URL/api.rsc
4. Select Generic Credentials and specify the Connect Server username and authentication token
5. Select the entity you wish to visualize
6. Select fields and choose a chart type
