XDMIC combines logic programming with relational database. This paper presents PCRF approach for model description and management-Predicates Calculus to readresent the model and to generate solving programs and Relational Framework to manipulate models and establish a model dictionary. PCF approach implements the division of the model with its solving program and the formalization of the model interpretation, and applies artificial intelligence and database to intelligent modeling and model management.展开更多
