Data Foundations (CMDB and CSDM) case studies
Data Foundations (CMDB and CSDM) · Put your knowledge to work in context.
Data Foundations (CMDB and CSDM) is an independent study credential for people who work with configuration data in the ServiceNow ecosystem, or who need to demonstrate that they understand how a Configuration Management Database is structured before touching it. It suits CMDB administrators, configuration and asset managers, service mapping practitioners, process owners, and analysts who report on service health. The exam spans seven domains: CMDB fundamentals, configuration items and the configuration management system, the purpose and scope of the Common Service Data Model, CSDM domains and layers including foundational data, data governance and health, relationship modeling and service mapping, and reporting and value realization. Expect conceptual questions more than product trivia: why a class hierarchy exists, what makes a relationship meaningful, how CSDM layers build on each other, and what good data health looks like. The Data Foundations (CMDB and CSDM) case studies are 5 cases and about 1,564 words.
