AI总结：
针对现有数据库建模工具存在成本、设置复杂度、可用性及系统依赖等问题，葡萄牙科英布拉大学开发了免费网页端工具ONDA，支持ER图创建、物理模型可视化与多引擎SQL生成，已用于大学数据库教学，年服务超三百名学生。
摘要：
数据库建模是满足存储需求的一项核心活动。尽管开发者可使用多种数据库建模工具，但这些工具往往存在相关成本、设置复杂、可用性挑战，或是依赖特定操作系统的问题。本文提出由科英布拉大学开发的网页端工具ONDA，它支持创建实体-关系图、可视化物理模型，还能为多种数据库引擎生成SQL代码。ONDA可通过https://onda.dei.uc.pt免费获取，开发初衷是支持大学数据库课程的教学活动。截至撰写本文时，该工具每学年有三百多名大学生使用。
英文摘要：
Database modeling is a key activity towards the fulfillment of storage requirements. Despite the availability of several database modeling tools for developers, these often come with associated costs, setup complexities, usability challenges, or dependency on specific operating systems. In this paper we present ONDA, a web-based tool developed at the University of Coimbra, that allows the creation of Entity-Relationship diagrams, visualization of physical models, and generation of SQL code for various database engines. ONDA is freely available at https://onda.dei.uc.pt and was created with the intention of supporting teaching activities at university-level database courses. At the time of writing, the tool being used by more than three hundred university students every academic year.
