#### Implementation Approaches

CDA accommodates both code-free and programmatic implementations. While you can create data sources without writing code, understanding the underlying XML structure and coding principles provides deeper insights into CDA's functionality.

The beauty of CDA lies in its simplicity - whether you prefer visual tools or hands-on coding, you can effectively:

  • Configure data sources

  • Design custom queries

  • Transform data outputs

  • Create dashboard-ready datasets

This streamlined approach eliminates the need for complex data parsing, making dashboard development more efficient and accessible.

## 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, and the optional `goal` query parameter:

```
GET https://academy.pentaho.com/pentaho-ctools/c-tools/community-data-access.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
