In this chapter, you learned the basics about PDI jobs: what a Job is, what you can do with a Job, and how jobs are different from transformations. In particular, you learned to use a Job for sending emails, working with files, and running one or more transformations.
In addition, you learned the basics about what Kettle variables are and where to use them. In the next chapter, we will switch back to the world of PDI transformations, to learn all the details about reading and writing all kinds of files.
