+This script checks data completeness in the CMDB by identifying missing key fields (like `os` and `location`) across selected CI classes (e.g., servers, applications). It counts how many CIs exist per class and how many are missing each field, helping administrators quickly spot and address data quality issues. This supports CMDB health, audit readiness, and overall data reliability.

+This ServiceNow business rule script is designed to detect configuration drift in a Configuration Item (CI) by comparing its current state to the most recent baseline record stored in the cmdb_baseline table.
+
+What it Does – In Simple Terms:
+
+Gets the latest baseline for the current CI.
+Compares key fields (ram, cpu_count, os) between the current CI and the baseline.
+If differences (a "drift") are found:
+It logs the drift in a custom table (u_drift_log).
+It triggers an event (ci.drift_detected) to possibly notify or take further action.
