# Work with the Streamlined Data Refinery

The Streamlined Data Refinery (SDR) is a simplified and specific ETL refinery composed of a series of Pentaho Data Integration (PDI) jobs that take raw data, augment and blend it through the request form, and then publish it for report designers to use in Analyzer.

To introduce you to the SDR structure, we have created the Movie Ratings-SDR [sample](https://pentaho.app.box.com/SDRSample60). This sample was developed by Pentaho and is based on CTools.
