In this first chapter, you were introduced to Pentaho Data Integration. Specifically, you learned what Pentaho Data Integration is and you installed the tool. You were also introduced to Spoon, the graphical designer of PDI, and you created your first transformation.
As an additional exercise, you installed a MySQL server and the MySQL GUI tools. You will need this software when you start working with databases in Chapter 8.
Now that you've learned the basics, you're ready to begin creating your own transformations to explore real data. That is the topic of the next chapter.
