Flow has three major building blocks known as Element, Connector, and Resource. With the help of these blocks, you can easily develop Flows.

Element represents an action that Flow can use to display or collect information from the Flow user, create or update records, delete records, or loop logic. Element is, basically, used to manipulate the data. Connector is used to establish the path between the elements. Resource is used to hold the data that you can reference in your Flow.
Flow elements represent actions that Flow can execute such as Record Update, Record Lookup, Fast Lookup, Loop, Screen, and Decision. This is used to read, write, or delete data. Using the element (Screen), you can also display data and capture input from users. Use the Palette tab to drag and drop new elements onto your canvas. Once you add elements it will be available on the canvas and Explorer tabs. There are several types of elements available under the Palette tab. They are as follows:
From Chapter 2, Creating Flow through Point and Click, we will start using these elements.
Resources are used to hold the data that you can reference in your Flow. The Explorer tab displays the resources that you added to the Flow. To create new resources double-click on this tab. Global constants and system variables are automatically provided by the system. There are several types of resources available under the Resource tab. They are as follows:
From Chapter 2, Creating Flow through Point and Click, we will start using these resources.
A connector is used to establish the path between the Flow elements. A connector looks like an arrow that points from one element to another. There are several types of connectors available. They are as follows:
From Chapter 2, Creating Flow through Point and Click, we will start using these connecters.
