The Identification and Reconciliation module provides a centralized framework for
identifying and reconciling data from different data sources. It helps maintain the integrity of
the CMDB when multiple data sources such as Discovery, import sets, and manual entries are used to
create and update CI records.
The use of multiple sources increases the risk of introducing inconsistencies through
duplicate records. To maintain the integrity of the database, it is important to correctly
identify CIs and services so that new records are created only for CIs that are truly new to the
CMDB. Identification and Reconciliation helps you prevent duplication of CI records, reconcile
CI attributes, reclassify CIs, and allow only authoritative data sources to update the CMDB.
The identification process is domain aware. If the domain separation plugin has been
activated, then identification processes only those CIs in which the domain ID is identical to
the domain of the currently logged on user. If duplicate CIs exists across domains (including
parent and child domains), then those CIs will not be considered duplicate CIs because their
domain IDs do not match.
