Overview
CSDM Fundamentals covers the Common Service Data Model — ServiceNow's standard framework for organizing service-related data in the CMDB. It defines domains (Foundation, Design, Sell/Consume, Manage Technical Services, Manage Business Services) and lifecycle stages for services.
Why It Matters for the Exam
CSDM Fundamentals accounts for 11% of the CIS-DF exam. While it's the smallest domain by weight, understanding CSDM is essential because it provides the conceptual framework that organizes all CMDB data.
