A step represents a single processing task in a case. In each step, exactly one operator is applied.
Steps are represented by icons in the MiningMart workspace (the case editor).
Steps are applied to the data in a certain user-defined order, where the input of one step depends
on the output of the previous one. These dependencies are represented in the MiningMart
workspace by arrows. They form a Directed Acyclic Graph (DAG), that is, there must not
be any cyclic dependencies. You can give explanatory names to the steps of a case.
