In this chapter, we examined the project that was generated by the recorder and saw an explanation of the structure of the program flow (workflow). We understood the use of Sequences and the nesting of activities. We learned how to use the building blocks of a workflow, Flowchart, and Control flow (looping and decision making).

In the next chapter, we will learn techniques to use memory with variables, and we will also learn about using data tables to store and easily manipulate data in memory. The next chapter will also show how disk files (CSV, Excel, and so on) are used to persist data.
