# 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. --- # 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.
