Twelve Design Patterns for Integrating and Normalizing Product Model Schemas

This article reviews a method for generating a product model from user data and introduces 12 design patterns for resolving conflicts that may occur in the integration and normalization process. The generating method and design patterns were evaluated during a project to integrate the product models collected from three different precast concrete companies in the United States, testing the new method of product model generation. The application results indicate that the 12 design patterns are effective and sufficient for resolving most known schema conflicts and for integrating and normalizing multiple product models into a single well-formed
