The Key problems in product modeling for integrated CAD//CAM systems are the information structures and representations of products. They are taking more and more important roles in engineering neplications. With the investigation on engineering product information andfrom the view point of industrial process, in this paper, the information models are proposed and the definitions of the framework of product information are given. And then, the integration and the consistence of product information are discussed by introducing the entity and its instance. As a summary, the information structures described in this paper have many advantages and natures helpful in engineering design.
