CSDM 3.0 is an evolution of the data model standard that supports the CMDB framework within the Now platform. Updates of the CSDM became necessary as the model itself had evolved.
To describe CSDM, we need to look at it more closely. Its value and use cases are multidimensional. An overview in one or two sentences simply does not do it justice.
- Centered around the concept of a service
- A collection of out-of-the-box (OOB) ServiceNow tables
- A framework of five areas supporting an end-to-end (E2E) service lifecycle
- Supported by guidelines for normative implementation and product use cases
Furthermore, the CSDM is not:
- A guide for process or product implementation (e.g. ITSM, ITOM, ITBM, etc.)
- A package, application or plugin to be installed
- A series of reports
- An automatic correction for previous implementations
- A SKU or a product sold by ServiceNow
The best place to start are the "Domains. There are four color-coded domains, each representing the capability to support the E2E service lifecycle.
The following diagram summarizes the focus of each domain.
The Common Service Data Model (CSDM) contains the areas Foundation, Design, Manage Technical Services, Sell/Consume and Manage Portfolio. Each domain is associated with one or more products or services.
The domain Foundation represents tables containing basic data referenced from or to objects in the other CSDM domains.
The design domain includes the tables currently used by ServiceNow® Application Portfolio Management (APM).
Manage Technical Services-Domain
This domain includes the tables currently used by ServiceNow® IT Operations Management (ITOM), such as Service Mapping and Discovery.
The sell/consume area includes the tables currently used by ServiceNow® Service Portfolio Management (SPM) and Customer Service Management.
Manage Portfolio Domain
This area includes parts of the other GSVM areas: Creation, design, management of technical services and sale/consumption.
