Chapter 12 Creating Mappings
You create a data source to define where (in which model) data should be extracted and transferred to another model.
When you define a data source, you have to declare available models in the list of data source models. A data source can contain several models, you can select the source models among a list of models open in the current workspace. All the selected models represent the same data source.
A model can contain several data sources.
