# How does SDR work?

The components that make up the data refinery are PDI, used for parameter entry, working in conjunction with an app for refining the data. This app calls to the Pentaho Server for the main job: refining data through Spoon using the new [Build Model](https://github.com/pentaho/documentation/blob/main/PDIA/9.3/PDI/Advanced%20Pentaho%20Data%20Integration%20topics/Advanced%20topics%20\(Pentaho%20Data%20Integration%20overview\)/Work%20with%20the%20Streamlined%20Data%20Refinery/Use%20the%20Streamlined%20Data%20Refinery/Building%20blocks%20for%20the%20SDR/Use%20the%20Build%20Model%20job%20entry%20for%20SDR=GUID-7FAB840B-9B79-440E-AE59-31C3F5B5EACA=4=en=.md) job entry, then publishing the data source back to the Pentaho Server through the [Publish Model](/pdia-data-integration/9.3-data-integration/advanced-topics-pentaho-data-integration-overview/work-with-the-streamlined-data-refinery/use-the-streamlined-data-refinery/building-blocks-for-the-sdr/using-the-publish-model-job-entry-for-sdr.md) job entry. Once it is published, the refined data is available for use in creating Analyzer reports. This process is shown in the graphic.

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://docs.pentaho.com/pdia-data-integration/9.3-data-integration/advanced-topics-pentaho-data-integration-overview/work-with-the-streamlined-data-refinery/how-does-sdr-work.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
