# Data Lineage

### Overview 

Data Lineage provides visibility into how data moves through the platform and how datasets and data assets are related. It helps users understand the relationship between source data, datasets, data models, and downstream analytical assets. 

Lineage improves transparency and supports impact analysis, data discovery, and governance by allowing users to understand where data originates and how it is used. 

### Key Capabilities 

* Trace data from its source through downstream datasets and data assets. 
* Understand relationships between datasets and data models. 
* View upstream and downstream dependencies. 
* Support impact analysis when datasets or data elements are changed. 
* Improve transparency and understanding of data flows. 
* Support data governance and data discovery activities. 

### How to Use Data Lineage 

Step 1: Select a Data Asset 

Select the relevant data source, dataset, or other supported data asset. 

Step 2: View Lineage 

Open the lineage information associated with the selected asset. 

Step 3: Explore Dependencies 

Review the upstream and downstream relationships to understand where the data originates and where it is being used. 

Step 4: Trace the Data Flow 

Follow the lineage across the available data assets to understand the movement and transformation of data. 

Step 5: Perform Impact Analysis 

Use the lineage information to identify downstream dependencies before making changes to a source, dataset, or data model.

### Outcome&#x20;

Data Lineage provides visibility into where data comes from, how it flows through the platform, and where it is consumed, supporting data discovery, governance, and impact analysis.&#x20;

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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://whiteklay.gitbook.io/virtual-data-assistant/how-to-guides/data-catalog/data-lineage.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.
