The invention provides a data management system and management method of a high-precision map, a terminal, and a storage medium. Feature elements in the high-precision map are collected as a feature element set according to semantic classification thereof, and positions, geometric attributes, physical attributes and/or semantic attributes of the feature elements are recorded. When an application level calls the map, an engine integrates the feature elements required to be described around a track coordinate, a description planning model plans a relative space relation between a planned path and a road unit, and when a vehicle is close to the feature element, a decision control module is assisted to make a corresponding decision/control response according to the coordinate position of the feature element and the semantics of the feature element. Besides, the feature elements in the high-precision map are collected as the feature element set according to the semantic classification thereof, classification update and management of a database of the high-precision map can be facilitated, and specific semantic classification can be preferably updated or iterated with high frequency.
