Data Dictionary

Overview

The Data Dictionary module is used to manage universal dictionary data within the system, using a two-level classification structure: the left side shows dictionary categories, and the right side shows dictionary items under the selected category. Dictionary data is commonly used in dropdown selects, multi-selects, cascading selects, and other scenarios, such as order status, user type, and region options. Through dictionary management, enumeration values in business logic can be centrally managed for easier maintenance and extensibility.
