Context Graph stages in dataflows
You add Context Graph stages to dataflows created in either Enterprise Designer or Flow Designer. These stages may also be incorporated in service dataflows, which can be accessed as web services or using the Spectrum Technology Platform API.
Context Graph stages perform operations on Context Graph models. The following Context Graph stages may be added to dataflows in either Enterprise Designer or Flow Designer.
