A configuration controls settings such as the default Data Integration Service, number of rows to read from a source, default date/time format, and optimizer level. The configurations that you create apply to your installation of the Developer tool.

You can create the following configurations:

Data viewer configurations. Control the settings the Developer tool applies when you preview output in the
Data Viewer
view.
Mapping configurations. Control the settings the Developer tool applies when you run mappings through the
Run Configurations
dialog box or from the command line.
Web service configurations. Controls the settings that the Developer tool applies when you preview the output of a web service in the
Data Viewer
view.
