论文摘要
当概念建模缺乏本体论的清晰度和严格的定义时,就会出现困难,这在关系结构中尤其如此。有证据表明,在传达应用程序领域的含义形式时,使用关系通常是有问题的。对该主题的研究很重要,因为关系对于多种方法至关重要,并且是从业者常用的。在本文中,我们在概念建模的背景下研究了关系或关系的概念。具体而言,我们关注实体关系(ER)模型中使用的关系的概念。 ER模型通过称为Thinging Machine(TM)的新形式的概念建模进行审查,以进一步了解关系概念的语义。 ER模型由三个基本类别(即实体,关系和属性)组成,而TM是由一个称为Thing/Machine(Thimac)的本体论类别构建的。几个ER图被重新铸造为TM图,从而产生了一个对概念模型中关系概念状态的有趣含义的分类碰撞。重新建模表明,关系构建体被消散到事物的TM流和事件的年表中。
Difficulties arise when conceptual modeling lacks ontological clarity and rigorous definitions, which is especially the case in the relationship construct. Evidence shows that use of relationships is often problematic when it comes to communicating the form of meaning of an application domain. Research on this topic is important because relationships are central to a number of approaches and commonly used by practitioners. In this paper, we study the notion of relation or relationship in the context of conceptual modeling. Specifically, we focus on the notion of relationship used in the entity-relationship (ER) model. The ER model is scrutinized through a new form of conceptual modeling called the thinging machine (TM) to pursue further understanding of the semantics of the relationship concept. The ER model is composed of three fundamental categories (i.e., entity, relationship and attribute), whereas TM is built from one ontological category called the thing/machine (thimac). Several ER diagrams are re-casted as TM diagrams, creating a categorical collision with interesting implications regarding the status of the conception of relationship in a conceptual model. The re-modeling shows that the relational construct is dissipated into TM flows of things and chronology of events.
