The Sys_dictionary table in ServiceNow plays a critical role in the schema management of the platform by storing metadata about the fields present in various tables. This includes detailed information on field attributes and properties such as field type, column name, maximum length, and whether the field is mandatory. This metadata is essential for understanding how each field behaves within its respective table, including how data can be entered and validated. Understanding this context clarifies the significance of the Sys_dictionary table. It serves as the backbone for the configuration and behavior of application tables, making the information it contains crucial for developers and administrators who are tasked with customizing and managing applications within ServiceNow.
