Final answer:
In the context of the Common Service Data Model (CSDM), the glue that ties all elements together, especially regarding applications, is the Application Service. It aligns technical services and components with business processes, providing a structured approach within a ServiceNow environment.
Step-by-step explanation:
The "glue" that ties all the elements of the Common Service Data Model (CSDM) together, particularly where applications are present, is typically defined as a set of best practices for organizing the various types of data and relationships in a ServiceNow environment. This model includes foundational elements like business services, applications, and infrastructure, ensuring data is structured in a way that supports service management processes.
At the heart of the CSDM, the Application Service functions as the glue. It links the different technical services, components, and configurations to the business services and capabilities they support. In this context, an Application Service is an application or a set of applications that support a business process or function, and it provides a way to visualize the impact of changes or issues on business services.
