Step

Fully qualified class name: DDICDIModels::DDICDILibrary::Classes::Process::Step

Definition

Step is a reusable, parameterized activity associated to information flows. One or more steps perform an sctivity.

Examples

An editing activity resolves into one or more steps. A transformation of a wide data set to a long data set 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.

One or more steps perform an sctivity.\n\nExamples\n==========\nAn editing activity resolves into one or more steps. A transformation of a wide data set to a long data set takes a single step on an ETL (extract, transform, load) platform like Pentaho.\n\nExplanatory notes\n===================\nSteps can be broken out into a sequence of sub steps ad infinitum."@en;
