Abstract

UML Interactions represent one of the three UML behaviors. They describe the interwork of parts of a system based on message exchange. UML Interactions can reside on any level of abstraction and they seem sufficiently elaborated for high-level specifications used for sketching the communication among parts of a system. The UML Interactions metamodel, however, reveals some deficiencies for precise specifications of data values and data flows. Even UML 2.5 still does not provide concepts for data flows in UML Interactions. In this paper, we suggest a profile-based extension that integrates data flow concepts with UML Interactions. The extension supports accessing (usage of) values located in data sources and assignment (definition) of values to data sinks in the context of message exchange and invocation of Interactions. The proposed extension improves the expressiveness of UML Interactions in a minimal invasive manner and makes it similar to the capabilities of UML Activities regarding the specification of data flows.

启用UML交互中的数据流

UML交互表示三种UML行为之一。它们描述了基于消息交换的系统各部分的相互作用。UML交互可以驻留在任何抽象级别上，并且对于用于绘制系统各部分之间通信草图的高级规范来说，它们似乎已经得到了充分的阐述。然而，UML interaction元模型在数据值和数据流的精确规范方面显示出一些缺陷。即使是UML 2.5也没有为UML交互中的数据流提供概念。在本文中，我们建议一个基于概要文件的扩展，它将数据流概念与UML交互集成在一起。该扩展支持访问(使用)位于数据源中的值，并在消息交换和交互调用的上下文中将值赋值(定义)给数据接收器。建议的扩展以最小的侵入性方式改进了UML interaction的表达性，并使其与UML Activities在数据流规范方面的功能相似。
