# Common Services Data Model (CSDM) is a ServiceNow best-practice framework that standardizes how IT services, applications, and infrastructure are structured in the CMDB. It provides a blueprint for aligning ServiceNow configurations with business and IT operations.
Why CSDM is Important:
* Ensures consistency in IT service mapping and asset relationships.
* Helps organizations align CMDB data with ITSM, ITOM, and other ServiceNow applications.
* Provides data governance and best practices to maintain data integrity.
* Option B (CMDB) is incorrect because the CMDB is the database that stores configuration items (CIs), but CSDM defines the model for structuring it.
* Option C (ITSM) is incorrect because ITSM includes processes like Incident, Problem, and Change Management, but does not provide a data model blueprint.
* Option D (ServiceNow Wiki) is incorrect because ServiceNow no longer uses a wiki for documentation (it has been replaced by the ServiceNow Docs Portal).
