摘要
数据建模是软件设计中的重要组成部分,计算机专业学生需要根据业务流的要求反复修改数据概念模型,并修改数据库及程序。文章提出了一种根据业务流的变化动态修改概念数据模型的方法,可以在不修改数据库的情况下通过软件编程完成数据模型的转换。这一方法可以提高学生进行系统开发实践的学习效率,也可以降低部署软件原型系统的难度和成本,是进行软件开发教学和开发中小型软件的一种有效设计方法。
Data modeling is an important part in the software design, students from computer science need to modify the conceptual data model according to the requirements of the business flow, and modify the database and program. This paper presents a method to modify the conceptual data model dynamically according to the change of the business flow. This method can improve students＇ learning efficiency of the system development practice, and reduce the difficulty and cost of the deployment of the softw-are prototype system. So it is an effective design method for software development teaching and development of small and medium-sized software.
