Use CData Connect AI to connect to OData Services from Cognos Analytics and analyze live OData services.

Cognos Analytics, powered by IBM Watson®, empowers users to cleanse and establish connections with their data while creating visualizations. When integrated with CData Connect AI, users gain immediate, real-time connectivity between cloud-based data sources and Cognos Analytics, facilitating data management, visualization, analytics, and more. This article provides step-by-step guidance on connecting to OData via CData Connect AI and subsequently analyzing OData services within Cognos Analytics.

NOTE: These instructions require Cognos Analytics 11.2.4 or higher

CData Connect AI offers a dedicated cloud-to-cloud interface for OData, enabling users to perform real-time analysis on OData services within Cognos without the need to replicate data to a natively supported database. Equipped with built-in optimized data processing capabilities, CData Connect AI efficiently directs all supported SQL operations, including filters and JOINs, directly to OData. This harnesses server-side processing to promptly provide the requested OData services.

About OData Data Integration

CData simplifies access and integration of live OData services data. Our customers leverage CData connectivity to:

  • Access OData versions 2.0, 3.0, and 4.0, working with legacy services and the latest features and capabilities.
  • Leverage advanced query options, including $filter, $select, and $expand, enhancing data retrieval from 3rd party tools.
  • Use Server-side execution of aggregation and grouping to minimize data transfer and boost performance.
  • Authenticate securely using a variety of schemes, including Azure AD, digest, negotiate, NTLM, OAuth, and more means secure authentication with every connection.
  • Use SQL stored procedures to manage OData service entities - listing, creating, and removing associations between entities.

Customers use CData's solutions to regularly integrate their OData services with preferred tools, such as Power BI, MicroStrategy, or Tableau, and to replicate data from OData services to their databases or data warehouses.


Getting Started


Configure OData Connectivity for Cognos Analytics

Connectivity to OData from Cognos Analytics is made possible through CData Connect AI. To work with OData services from Cognos Analytics, we start by creating and configuring a OData connection.

  1. Log into Connect AI, click Sources, and then click Add Connection
    2. 👁 Adding a Connection
  2. Select "OData" from the Add Connection panel
    3. 👁 Selecting a data source
  3. Enter the necessary authentication properties to connect to OData.

    The User and Password properties, under the Authentication section, must be set to valid OData user credentials. In addition, specify a URL to a valid OData server organization root or OData services file.

  4. Click Save & Test
  5. Navigate to the Permissions tab in the Add OData Connection page and update the User-based permissions. 👁 Updating permissions

Add a Personal Access Token

When connecting to Connect AI through the REST API, the OData API, or the Virtual SQL Server, a Personal Access Token (PAT) is used to authenticate the connection to Connect AI. It is best practice to create a separate PAT for each service to maintain granularity of access.

  1. Click on the Gear icon () at the top right of the Connect AI app to open the settings page.
  2. On the Settings page, go to the Access Tokens section and click Create PAT.
  3. Give the PAT a name and click Create. 👁 Creating a new PAT
  4. The personal access token is only visible at creation, so be sure to copy it and store it securely for future use.

With the connection configured and a PAT generated, you are ready to connect to OData services from Cognos Analytics.

Connect to OData from Cognos Analytics

The steps below outline connecting to CData Connect AI from Cognos Analytics to analyze live OData services.

Download and install the CData Connect AI JDBC driver

  1. Open the Integrations page of CData Connect AI.
  2. Search for and select JDBC.
  3. Download and run the setup file.
  4. When the installation is complete, copy the JAR file (cdata.jdbc.connect.jar) from the installation directory (e.g., C:\Program Files\CData\JDBC Driver for CData Connect\lib) to the "drivers" folder in your Cognos Analytics installation directory.

Configure the Connection to CData Connect AI

  1. Open IBM Cognos and navigate to Manage > Data server connections.
  2. Click the icon to add a data server.
  3. Select CData Connect AI.
  4. Set JDBC URL to the appropriate connection string. For example: 
     jdbc:connect:AuthScheme=Basic;user=username;password=PAT;
  5. Set Driver class name to "cdata.jdbc.connect.ConnectDriver"
  6. Create and store authenticate credentials by selecting an authentication method
    • Set Username to your CData Connect AI username (e.g., [email protected])
    • Set Password to the PAT you previously generated.
  7. Click Test connection to confirm that the connection succeeds. 👁 Connecting to CData Connect AI from Cognos Analytics
