物化是一种有用的抽象模式，可以在许多应用程序设置中识别。直观地说，物化是一类类别(例如，汽车模型)和一类更具体的对象(例如，单个汽车)之间的关系。本文根据通常的IS-A和ISOF抽象以及类/元类对应给出了物化的准形式化语义定义。新的和强大的继承机制与物化相关。文中还给出了物化的实例、性质和扩展。通过在应用程序级别有控制地引入分类，将物化作为概念建模的抽象机制来增强表现力。
Materialization is a useful abstraction pattern that can be identified in many application settings. Intuitively, materialization is the relationship between a class of categories (e.g., models of cars) and a class of more concrete objects (e.g., individual cars). This paper gives a quasi-formal semantic definition of materialization in terms of the usual is-a and isof abstractions, and of a class/metaclass correspondence. New and powerful inheritance mechanisms are associated with materialization. Examples, properties, and extensions of materialization are also presented. Providing materialization as an abstraction mechanism for conceptual modeling enhances expressiveness by a controled introduction of classification at the application level.
