On the basis of no change the model structure,from the semantics description viewpoint,based on the principles for model expanding and optimization indexes to determine the extended objects,adopt the form of standard extention of reference entities,through semantic constraints to response changes and needs of the business.So the logical model's practicality,stability and sustainability is ensured.
