It helps maintain the integrity of the CMDB and some non-CMDB tables when multiple data sources are used to create and update CI records.{#c_CMDBIdentifyandReconcile__ph_IDandReconcileShortDesc} ## Get started {#c_CMDBIdentifyandReconcile__cf-app-landing-get-started} |-|-|-| | [ExploreLearn about benefits and how IRE helps maintain the integrity of the CMDB.](https://servicenow-prod.fluidtopics.net/5zLY2C2JufI9Y1b0e8GoHQ "The Identification and Reconciliation (IRE) module provides a centralized framework for identifying and reconciling data from different data sources.
