# Identifying datasets dependencies

Using dataset dependencies is a great way to:

* Understand the impact of an action on a dataset (edit, delete, duplicate...) on other datasets and visualizations
* Navigate between depending datasets
* Identify unused datasets (not tied to any visualizations) to clean them

To see dependencies on a dataset, check the dependency column within the dataset list in the DataHub, Dataset section.

For a given dataset you will find the depending:

* Datasource(s): connector or files used by the dataset or a parent dataset
* Parent dataset(s): dataset(s) used to create this dataset or another parent dataset
* Child dataset(s): dataset(s) created on top this dataset or another child dataset
* Home or stories: home tiles or story charts using this dataset or a child dataset

# 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-v3.toucantoco.com/data-management-in-datahub/datasets-in-toucan/maintaining-data/identifying-datasets-dependencies.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.
