IBM Data Virtualization connection

IBM Data Virtualization connection

To access your data in Watson Query, create a connection asset for it. A Data Virtualization connection is created automatically in a catalog or project when you publish a virtual object to a catalog or assign it to a project. The IBM Watson Query connection was formerly know as the Watson Query connection.

Watson Query integrates data sources across multiple types and locations and turns all this data into one logical data view. This virtual data view makes the job of getting value out of your data easy.

Create a Data Virtualization connection

To create the connection asset, you need these connection details:

Credentials

Connecting to a Watson Query instance in IBM Cloud

  • API key: Enter an IAM API key. Prerequisites:
    1. Add the user ID as an IAM user or as a service ID to your IBM Cloud account. For instructions, see the Console user experience section of the Identity and access management (IAM) on IBM Cloud topic.
    2. The Watson Query Manager of the Data Virtualization instance must add IAM users by selecting Data > Data Virtualization > Administration > User management from the Cloud Pak for Data as a Service navigation menu.

Connecting to a Watson Query instance in Cloud Pak for Data (on-prem)

  • User credentials: Enter your Cloud Pak for Data username and password.
  • API key: Enter an API key value with your Cloud Pak for Data username and a Cloud Pak for Data API key. Use this syntax: user_name:api_key
  • Use my platform login credentials. This option is available If you select Personal credentials and the User credentials authentication method. The Watson Query service must be deployed on the same instance of Cloud Pak for Data where you are creating the connection. With platform credentials, the connection to Watson Query is established by using your current session JSON Web Token (JWT).

For Private connectivity, to connect to a database that is not externalized to the internet (for example, behind a firewall), you must set up a secure connection.

Choose the method for creating a connection based on where you are in the platform

In a project
Click Assets > New asset > Connect to a data source. See Adding a connection to a project.
In a catalog
Click Add to catalog > Connection. See Adding a connection asset to a catalog.
In a deployment space
Click Import assets > Data access > Connection. See Adding data assets to a deployment space.
In the Platform assets catalog
Click New connection. See Adding platform connections.

Next step: Add data assets from the connection

Where you can use this connection

You can use Data Virtualization connections in the following workspaces and tools:

Projects

  • Data quality rules (IBM Knowledge Catalog)
  • Data Refinery (Watson Studio or IBM Knowledge Catalog)
  • DataStage (DataStage service). See Connecting to a data source in DataStage.
  • Decision Optimization (Watson Studio and Watson Machine Learning)
  • Metadata enrichment (IBM Knowledge Catalog)
  • Metadata import (IBM Knowledge Catalog)
  • SPSS Modeler (Watson Studio)

Catalogs

  • Platform assets catalog

  • Other catalogs (IBM Knowledge Catalog)

Connected assets in governed catalogs can be used for the enforcement of data protection rules in Watson Query.
