Abstract—The most popular tools for developing object-oriented information systems are CASE-tools. More often, they do not support n-ary association relationships between classes. It is shown how, when describing a domain model, one can go from n-ary associations to binary ones, how to reduce the number of information system objects, and how to take into account the restrictions placed on objects. Situations that allow this kind of transformation are presented in the form of design patterns.

为设计信息系统建模统一语言模板

摘要-用于开发面向对象的信息系统的最流行的工具是CASE工具。通常，它们不支持类之间的n元关联关系。它说明了如何在描述域模型时从n元关联变为二元关联，如何减少信息系统对象的数量以及如何考虑对对象的限制。允许这种转换的情况以设计模式的形式呈现。
