Chapter 10. Creating Basic Task Flows

So far, you have been working with data. Basically, you got data from a file, a sheet, or a database, transformed it somehow, and sent it back to some file or table in a database. You did it by using PDI transformations. A PDI transformation does not run in isolation. Usually, it is embedded in a bigger process. Here are some examples:

• Download a file, clean it, load the information of the file in a database, and fill an audit file with the result of the operation.
• Generate a daily report and transfer the report to a shared repository.
• Update a data warehouse. If something goes wrong, notify the administrator by e-mail.

All these examples are typical processes in which a transformation is only a part. These types of processes can be implemented by PDI jobs. In this chapter, you will learn how to build basic jobs. These are the topics that will be covered:

• Introduction to jobs
• Executing tasks upon conditions
• Working with arguments and named parameters...
