In the previous chapters, you were introduced to PDI transformations, the PDI artifacts meant to deal with data. Usually, you don't run a PDI Transformation isolated; you embed it 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 an email
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 particular, one of the tasks of those jobs will be executing one or more transformations. This execution can be done with a special Job entry, the transformation entry.
