CData Connect



Use the CData Connect Cloud to create an OData API on top of Oracle data and visualize live Oracle data in Ingragistics Reveal.

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

Add a Connect Cloud User

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

    To connect to Oracle, you'll first need to update your PATH variable and ensure it contains a folder location that includes the native DLLs. The native DLLs can be found in the lib folder inside the installation directory. Once you've done this, set the following to connect:

    • Port: The port used to connect to the server hosting the Oracle database.
    • User: The user Id provided for authentication with the Oracle database.
    • Password: The password provided for authentication with the Oracle database.
    • Service Name: The service name of the Oracle database.
  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 Oracle OData Endpoints in Connect Cloud

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

  1. Click OData -> Tables -> Add Tables
  2. Select the Oracle 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 Cloud configured, we can visualize Oracle data in Reveal.

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