Data is the key to success for any Data-Driven Organization, and managing it is considered the most challenging task. Data Architecture (DA) focuses on describing, collecting, storing, processing, and analyzing the data to meet business needs. In this tool demo paper, we present the DAT, a model-driven engineering tool enabling data architects, data engineers, and other stakeholders to describe how data flows through the system and provides a blueprint for managing data that saves time and effort dedicated to Data Architectures for IoT applications. We evaluated this work by modeling five case studies, receiving expressiveness and ease of use feedback from two companies, more than six researchers, and eighteen undergraduate students from the software architecture course

翻译：数据是任何数据驱动型组织成功的关键，而管理数据被认为是最具挑战性的任务。数据架构主要关注数据的描述、收集、存储、处理和分析，以满足业务需求。在本文的工具演示中，我们介绍了DAT，这是一个模型驱动工程工具，使数据架构师、数据工程师及其他利益相关者能够描述数据如何在系统中流动，并为管理数据提供蓝图，从而节省用于物联网应用数据架构的时间和精力。我们通过对五个案例研究进行建模来评估这项工作，收到了两家公司、六位以上研究人员以及软件架构课程中十八名本科生关于表达力和易用性的反馈。
