What table provides a complete view of all the components installed in an application scope?

The table that provides a complete view of all the components installed in an application scope is the sys_metadata table. This table holds metadata about various elements within the application, such as scripts, business rules, and UI policies, and is crucial for understanding the structure and components functioning together in that specific application scope.

The sys_dictionary table contains definitions for fields on all tables in ServiceNow, providing attributes and characteristics for each field but does not summarize installed application components. The sys_scope table is used to define application scopes but does not detail the specific components within each scope. The sys_applications table includes records of the applications but focuses more on the applications as entities rather than providing a breakdown of the individual components.

Thus, the sys_metadata table is the appropriate choice for someone looking to gain insights into all elements and their relationships within an application scope.
