Definition

Step is a reusable, parameterized Activity associated to InformationFlows. One or more Steps perform an Activity.

Examples

An Editing Activity resolves into one or more Steps. A transformation of a WideDataSet to a LongDataSet takes a single Step on an ETL (extract, transform, load) platform like Pentaho.

Explanatory notes

Steps can be broken out into a sequence of sub steps ad infinitum.
