The boundary line between a beginner and an intermediate KNIME user is often defined by their understanding of the concept of Flow Variables. Without flow variables you can only create simple static workflows - useful for automation and data processing, of course, but limited in their applicability. With flow variables, however, the sky is the limit in developing sophisticated and parametric workflows.
The parameterization introduced by flow variables allows your workflow to execute with different input values - for example, selecting the top customer of a particular month for a custom report - all without specifying the value manually in the affected nodes. Believe us, the concept of flow variables is revolutionary! It can take your KNIME skills to a whole new height - join us to learn practical ways to implement them.
