Chapter 16 The Mapping Editor

Source pane

The Source pane displays all the data sources and their source models showing all the objects that can be mapped.

You need to create at least one data source and declare models in the list of data source models to define where (in which database or model) data should be extracted to be transferred to the model in the Target pane. You can create several data sources.

A data source can contain several models, you can select the source models among a list of models open in the current workspace.

The Source pane always displays a gray background ; it is primarily displayed on the left in the Mapping Editor. However, the Source pane is displayed on the right pane in case of reverse mapping editing.

For more information about reverse mapping, see the "Understanding the Mapping Editor Dialog Box" section.

The following toolbar helps you manage sources:

Tool	Name	Description
	Properties	Opens the property sheet of the selected source object.
	Create Data Source	Launches the Data Source Creation Wizard that allows you to name a data source, specify an access type and select source models. When the target model is an XSM, you can also select the model type being used as data source.
	Delete Data Source	Deletes the selected data source. Related mappings, if any, are automatically deleted.
	Add Model to Data Source	Adds one or more source models to an existing data source from a selection dialog box.
