Supported Relational Databases


D s platform
 can natively connect to these relational database platforms. Natively supported Supported versions are the following:

  • Oracle
  • SQL Server 12.0.4
  • PostgreSQL 9.3.10
  • Teradata 14.10+


    NOTE: To enable Teradata connections, you must download and install Teradata drivers first. For more information, see Enable Teradata Connections.

Additional relational connections can be enabled and configured for the platform. For more information, see Connection Types.


For any relational source to which you are connecting, the 

D s node
 must be able to access it through the specified host and port value.

Please contact your database administrator for the host and port information.


This feature is enabled automatically. 

To disable:

To prevent users from connecting to relational datasources for importing datasets and writing results, please complete the following configuration changes:


NOTE: Disabling this feature hides existing relational connections.

  1. D s config
  2. Locate the following setting:

    Code Block
    Connectivity feature

  3. Set this value to Disabled.

Disable relational publishing

By default, relational connections are read/write, which means that users can create connections that enable writing back to source databases.

  • When this feature is enabled, writeback is enabled for all natively supported relational connection types. See Connection Types.
  • Depending on the connection type, the
    D s platform
    writes its data to different field types in the target database. For more information, see Type Conversions.
  • Some limitations apply to relational writeback. See Limitations below.

As needed, you can disable this feature.


  1. D s config
  2. Locate the following parameter and set it to false:

    Code Block
    "webapp.connectivity.relationalWriteback.enabled": true,

  3. Save changes and restart the platform.

Publishing through relational connections is disabled.



NOTE: Unless otherwise noted, authentication to a relational connection requires basic authentication (username/password) credentials.

  • You cannot swap relational sources if they are from databases provided by different vendors. See Flow View Page.
  • There are some differences in behavior between reading tables and views. See Using Databases.



NOTE: Writing back to the database utilizes the same user credentials and therefore permissions as reading from it. Please verify that the users who are creating read/write relational connections have appropriate access.


  • You cannot ad-hoc publish to a relational target. Relational publishing is only supported through the Run Job page.
  • You write to multiple relational outputs from the same job only if they are from the same vendor.
    • For example, if you have two SQL Server connections A and B, you can write one set of results to A and another set of results to B for the same job.
    • If A and B are from different database vendors, you cannot write to them from the same job.
