Abstract: This paper describes a product data model as a product structural tree that is composed of data objects and relation objects, and expresses the product structural tree as a matrix. It proposes that a product data model consists of many views with the design view as the core. The view projections of a product data model are isomorphic structural trees that can also be expressed as a matrix separately. A mapping matrix, an intersection matrix and a union matrix between two views are derived from the two corresponding view matrixes. This theory can be regarded as one of the basis of the further research and application for product data models.
