# Data views

Data views help you understand data assets before training or explanation work.

Use them to trace how data was produced and review the distribution of values in an onboarded dataset.

## Views by concern

### Lineage

[**Datasource lineage**](./datasource-lineage-view) shows lineage information for a datasource.

Use it when you need to understand where a datasource came from and how it relates to upstream data assets.

[**Dataset lineage**](./dataset-lineage-view) shows lineage information for a dataset.

Use it when you need to trace how an onboarded dataset was created and how it relates to its datasource or onboarding workflow.

### Distribution

[**Dataset histogram**](./dataset-histogram-view) describes the distribution of values in a dataset.

Use it when you need to inspect feature or target distributions, categorical frequencies, numeric bins, and target statistics before training or model review.
