A configuration Item (CI) is any component of an IT infrastructure that you want to be under the control of configuration management and therefore subject to change control. Change and Configuration Management Database (CCMDB) maintains two kinds of data about CIs: authorized CI data and actual CI data.
Configuration Items application — In this application you create configuration items that conform to rules and relationships that you specify. These configuration items are in effect "authorized" configuration items.
Actual CIs application — In this application you can view information about data collected directly from components actually installed in your enterprise. To gather this data, discovery tools scan computers, network devices, and other information technology components deployed in your enterprise and record information about the hardware and software installed on those components. Integration tools import the collected data into the database.
The Reconciliation module applications let you configure a behind-the-scenes process that reconciles authorized CI data against actual CI data and identifies successful matches as well as discrepancies and variances between the two. You can view the results of this reconciliation in the CI Link Results and CI Reconciliation Results applications.
