OData connection
Last updated: Nov 27, 2024
OData connection

To access your data in OData, create a connection asset for it.

The OData (Open Data) protocol is a REST-based data access protocol. The OData connection reads data from a data source that uses the OData protocol.

Supported versions

The OData connection is supported on OData protocol version 2 or version 4.

Create a connection to OData

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

  • Service root URL: The URL to access the service root of a site that has implemented the OData protocol. Consult the client product's documentation to confirm the Service root URL.
  • Timeout seconds: Timeout value for the HTTP calls.

Credentials type:

  • API Key
  • Basic
  • None

Encryption:
SSL certificate (if required by the database server)

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 the OData connection in the following workspaces and tools:

Projects

  • Data Refinery (watsonx.ai Studio or IBM Knowledge Catalog)
  • SPSS Modeler (watsonx.ai Studio)

Catalogs

  • Platform assets catalog

  • Other catalogs (IBM Knowledge Catalog)

OData setup

To set up the OData service, see How to Use Web API OData to Build an OData V4 Service without Entity Framework.

  • For SPSS Modeler, you cannot create new entity sets.
