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.

There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "You should specify the full path, for instance: C:/Pentaho/data/ny_cities."

A block of code is set as follows:

 SELECT full_name
, injury_type
, to_char(start_date_time, 'yyyy-mm-dd') as injury_date
FROM injury_phases i
JOIN display_names n ON i.person_id = n.id AND entity_type = 'persons'
AND start_date_time BETWEEN '2007-07-01' AND '2007-07-31'
ORDER BY full_name, injury_type 
 

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "You can save time by clicking the Get fields to select button, which fills the grid with all the incoming fields."
