Data VV&C of artificial Beijing system

As a most important part of modeling and simulation, data influences the reliability and credibility of model and system directly. First, this paper researches on the related concepts of data VV&C (verification, validation and certification) and analyzes the artificial Beijing system deeply. Then, According to the building process of human model in artificial Beijing, it expatiates on the process and key steps of input and output data VV&C, so as to provide a referable case for data VV&C and provide certain reference for the development and evaluation process of model and system as well.
