Summary

In this chapter, you created several transformations. As you did it, you got more familiar with the design process, including dealing with errors, previewing, and running transformations. You had the opportunity of learning several Kettle steps, and you also learned how to handle errors that may appear. At the same time, you learned the basic terminology related to data and transformations.

In all the sections of this chapter, you worked with dummy data. Now, you are prepared to work with real world data. You will learn how to do that in the next chapter.
