Creating the building blocks of Flow

In Chapter 1, Getting Started with Visual Workflow, we discussed the building blocks of Flow; for example, Flow elements, Flow resources, and Flow connectors. Before going ahead, you will first learn to create variables in Flow, and then we will discuss the other building blocks in upcoming chapters.

• Creating a variable
• Creating a collection variable
• Creating an SObject Variable
