# Compare Data

There are three ways to compare data: 

* The [**Comparison Tool**](https://docs.dqman.com/opentext-documentum-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 DQL query results or with imported data lists.
* The [**Object Compare List**](https://docs.dqman.com/opentext-documentum-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.
* [**Legacy Compare Data**](https://docs.dqman.com/opentext-documentum-edition-24.2/compare-data/legacy-compare-data) is the previous data comparator in dqMan 6, accessible via the options menu, will be phased out from dqMan's features in upcoming releases.
