# Work with transformations

In the [PDI client (Spoon)](/pdia-data-integration/10.2-data-integration/data-integration-perspective-in-the-pdi-client/basic-concepts-of-pdi.md), you can develop transformations, which are data workflows representing your ETL activities. The steps used in your transformations define the individual ETL activities. The transformations containing your steps are stored in KTR files. You can access these KTR files through the PDI client.
