Common Service Data Model (CSDM) CSDM is a standard methodology for populating the CMDB and other data tables in your ServiceNow instance. It provides a consistent set of terms and definitions, and also provides prescriptive guidance on where data should be placed. As a simple example, it requires IP addresses to be stored against network interface CIs rather than server CIs. By following the CSDM, you ensure that data is always where it’s expected to be. That means that your ServiceNow applications know where to find the data, and it also allows you to do accurate analytics and reporting on your infrastructure and services. If you use ServiceNow Discovery and Service Mapping to populate your CMDB, this automatically ensures that your CMDB conforms with the CSDM. If you use certified Service Graph connectors to import data from third-party systems, these are also CSDM-compliant. Also note that the CSDM isn’t limited to IT infrastructure and digital services. It provides a prescriptive framework across multiple information domains. For instance, it provides a standard model for contracts.
