How to read this book
Although it is recommended that you read all the chapters, you don't have to. The book allows you to tailor the PDI learning process according to your particular needs.
The first five chapters along with Chapter 10, Creating Basic Task Flows, cover the core concepts. If you don't know PDI and want to learn just the basics, reading those chapters will suffice. If you need to work with databases, you could include Chapter 8, Working with Databases, in the roadmap.
If you already know the basics, you can improve your PDI knowledge by reading Chapter 6, Transforming Your Data by Coding, Chapter 7, Transforming the Rowset, and Chapter 11, Creating Advanced Transformations and Jobs.
If you already know PDI and want to learn how to use it to load or maintain a data warehouse or datamart, you will find all that you need in Chapter 9, Performing Advanced Operations with Databases, and Chapter 12, Developing and Implementing a Simple Datamart.
Finally, all the appendices are valuable resources for anyone reading this book.
