数据库系统通常被认为是本科课程的一个令人兴奋的主题。为了弥补这一点，我们描述了一种新的交互式电子教科书本科数据库系统课程教学。专为触摸驱动的平板电脑，教科书嵌入了一个功能齐全的数据库。教科书中的表达、数字和解释是活的、互动的元素。与固定的插图和动画相反，学生可以与每个教科书元素进行交互。与数据库的快速反馈循环允许用户探索和理解对数据库的有效和无效查询的全部范围。无线连接使教师能够实时跟踪课堂表现，将教科书教学与课堂演示相结合，从而实现教室的扩展。我们讨论了这个概念的设计，并分享了在课堂上使用的原型实现的初步评价。
Database systems have often been considered an unexciting topic for undergraduate curricula. To remedy this, we describe a novel interactive electronic textbook for teaching undergraduate database systems courses. Designed for touch-driven tablets, the textbook embeds a fully capable database. Expressions, figures and explanations in the textbook are live, interactive elements. In contrast to canned illustrations and animations, students can interact with each textbook element. The rapid feedback loop with the database allows the user to explore and understand the full scope of valid and invalid queries to the database. Wireless connectivity allows the instructor to track classroom performance in real-time, merging textbook instruction with in-class demonstrations, allowing for the scaling out of classrooms. We discuss the design of this concept, and share a preliminary evaluation of a prototype implementation used in the classroom.
