Viewing Data Overview

You can run a mapping, view profile results, view source data, preview data for a transformation, run an SQL query, preview web service messages, or view dependencies on an object.
Run a mapping to move output from sources to targets and transform data. You can run a mapping from the command line or from the Run dialog box. View profile results in the editor.
You view source data, preview data for a transformation, run an SQL query, or preview web service messages in the Data Viewer view.
Note: The maximum number of rows you can preview in the Data Viewer is 100,000.
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.
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.
You can also view object dependencies when you view, modify, or delete Model repository objects. You can view object dependencies in the Object Dependencies view.
