应用程序集成需要考虑实例数据和模式数据。一个应用程序中的实例数据可能是另一个应用程序的模式数据，这会产生多个实例化级别。使用深度实例化，对象可以通过表示关于几个实例化级别下的对象的模式数据来深入表征。深度实例化仍然需要明确的实例化级别分离：关系的源对象和目标对象必须处于相同的实例化级别。在应用程序集成的上下文中，这种分离是不够的。另一方面，双重深度实例化(DDI)允许在不同实例化级别连接对象的关系。可以为关系的每一端分别指定表征的深度。在本文中，我们提出并实现了集合论的谓词和公理，用于用DDI表示概念模型。
Application integration requires the consideration of instance data and schema data. Instance data in one application may be schema data for another application, which gives rise to multiple instantiation levels. Using deep instantiation, an object may be deeply characterized by representing schema data about objects several instantiation levels below. Deep instantiation still demands a clear separation of instantiation levels: the source and target objects of a relationship must be at the same instantiation level. This separation is inadequate in the context of application integration. Dual deep instantiation (DDI), on the other hand, allows for relationships that connect objects at different instantiation levels. The depth of the characterization may be specified separately for each end of the relationship. In this paper, we present and implement set-theoretic predicates and axioms for the representation of conceptual models with DDI.
