Differentiation storage and dynamic generation method and system based on object model

The embodiment of the invention provides a differentiated storage and dynamic generation method and system based on an object model, and the method comprises the steps: obtaining to-be-stored object instances, and determining corresponding object class data and difference items between the object instances; establishing a mapping table, and extracting feature characters to obtain a feature character set corresponding to the mapping table; receiving real-time data, and judging whether the real-time data is real-time object class data or a real-time object instance; when the real-time data is real-time object class data, carrying out minimum semantic expressible storage on the real-time object class data, and generating a difference item list and a real-time mapping table in combination with an object instance; when the real-time object data is a real-time object instance, determining a real-time feature character; comparing the real-time feature characters with the feature character set, and when the real-time
