To get the most out of this book

PDI is a multiplatform tool, meaning that it can be installed and used under any operating system. The only prerequisite is to have JVM 1.8 installed. You will also need a good text editor, for example, Sublime III or Notepad ++. It's also recommended that you have access to a relational database. The examples in the book were built with PostgreSQL syntax, but you can adapt them to any other engine, as soon as there is a JDBC driver for it.
Throughout the chapters, several internet links are provided to complement what is explained. Therefore, having an internet connection while reading is highly recommended.
