概念数据库设计对于新手数据库设计者（例如学生）来说是一项艰巨的任务，因此对于数据库教育者来说也特别具有挑战性。在数据库设计的教学中，经常强调两种通用方法：自上而下和自下而上。在本文中，我们对学生在概念数据建模练习中这两种方法的表现进行了实证比较。我们的结果表明，虽然之前的数据库教育对设计性能的质量有显着影响，但所选择的方法却没有。研究结果表明，数据库教育者应该在数据库设计中整合自上而下和自下而上的方法，显示两种方法之间的差异和相似之处，以提高学生对数据建模的学习。
Conceptual database design is a difficult task for novice database designers, such as students, and is also therefore particularly challenging for database educators to teach. In the teaching of database design, two general approaches are frequently emphasized: top-down and bottom-up. In this paper, we present an empirical comparison of students’ performance between these two approaches in a conceptual data modeling exercise. Our results indicate that, while prior database education had a significant effect on the quality of design performance, the chosen approach did not. The findings suggest that database educators should integrate both top-down and bottom-up approaches in database design showing the differences and similarities between the two approaches to improve students’ learning of data modeling.
