Introduction

As this chapter focuses on basic visual programming tools, it is a good place to have a quick look at how the programming of workflows works.

A workflow is made up of several sections. This chapter's focus will be on the creation of new workflows. We will work with the general, inputs, outputs, schemas, and presentation.

Variables (general, inputs, and outputs)

Each workflow can have variables in three different areas. Variables are called attributes or parameters depending on where they are.
