# Compare Data

There are two ways to compare data: 

* The[ **Comparison Tool**](https://docs.dqman.com/veeva-vault-edition-24.2/compare-data/comparison-tool) function from the **Extras** menu enables you to compare different data lists,  for example DQL query results with other VQL query results or with imported data lists.
* The [**Object Compare List**](https://docs.dqman.com/veeva-vault-edition-24.2/compare-data/the-object-compare-list) enables you to add single objects of any type, from any repository. These objects are compared attribute by attribute and you can modify them directly in the list.
