What stores the structure and relationship definitions in ServiceNow?

  1. Sys_schema

  2. Sys_dictionary

  3. Sys_configuration

  4. Sys_tables

The correct answer is: Sys_dictionary

The correct answer is Sys_dictionary, which plays a crucial role in ServiceNow as it stores the definitions of the fields within tables. This includes detailed information about each field, such as its name, type, and any relationships it may have with other fields or tables. The Sys_dictionary table serves as a meta-definition of all tables in the ServiceNow instance, allowing users to understand data structures and enforce relationships effectively. This structure is imperative for the application development and customization process in ServiceNow, as it allows developers to create and manage their data models efficiently. By providing a reference point for how tables relate to one another, it ensures data integrity and supports the platform's functionality. The other options refer to different aspects of ServiceNow's architecture. Sys_schema pertains to database schemas, Sys_configuration relates to application configurations, and Sys_tables lists all the tables in the system but does not provide the specific structure and relationship details that Sys_dictionary does.
