# DataRules

The DataRules application gives you a highly configurable way of updating your Bullhorn data.

Below is a brief overview of the features in DataRules and notes on functionality.

This guide concentrates on the Candidate entity but all other entities function identically.

{% hint style="info" %}
Please be aware that Kyloe DataRules will follow the same functionality as Bullhorn. Any automation that occurs within Bullhorn will run when an update takes place. Updating a company address, for example, will update related client contact records even if not included in the actions for a rule. These additional updates **will not** be rolled-back if the [revert ](/kyloe-datatools/datarules/reverting-a-rule.md)functionality is used.
