The previous examples show typical uses of PDI as a standalone application. However, Kettle may be used embedded as part of a process or a data flow. Some examples are preprocessing data for an online report, sending emails in a scheduled fashion, generating spreadsheet reports, feeding a dashboard with data coming from web services, and so on.
The use of PDI integrated with other tools is beyond the scope of this book. If you are interested, you can find more information on this subject in the Pentaho Data Integration Cookbook - Second Edition by Packt Publishing at https://www.packtpub.com/big-data-and-business-intelligence/pentaho-data-integration-cookbook-second-edition.
