Use the

Data Viewer

view to view source data, preview data for a transformation, run an SQL query, or preview web service messages.

Before you can view data, you must select a default Data Integration Service if the domain includes more than one service.

You can also add other Data Integration Services to use when you view data.

You can create configurations to control settings that the Developer tool applies when you view data.

You can preview data within a mapping that runs on either the Data Integration Service or the Spark engine. You can choose sources and transformations as preview points in a mapping.

The Data Integration Service determines whether to run the job in the native environment or on the Spark engine based on the preview point. The preview point is the object in a mapping that you choose to view data for. For more information about data preview on the Spark engine see the

Data Engineering Integration User Guide

.

When you view data in the

Data Viewer

view, you can export the data to a file. You can also access logs that show log events.

Use the

Object Dependencies

view to view object dependencies when you view, modify, or delete Model repository objects.
