摘要
在软件实训教学过程中,对于在功能建模后如何抽象出系统数据模型,缺乏必要的过程指导,学生存在无从下手的问题。基于此,本文分析了从功能模型抽象出数据模型的完整过程,修复了从功能建模到数据建模间的漏洞,并举例对比了两者间容易混淆的概念,为正确定义软件系统的数据模型提供了必要的推演依据,符合软件工程逐步精细的思维过程。
In the process of software training and teaching, how students can abstract the system data model after functional modeling, lack of necessary process guidance, and there is a problem that they cannot start. Based on this, this article analyzes the complete process of abstracting the data model from the functional model, fixes the loopholes from the functional modeling to the data modeling, and compares the concepts that are easily confused between the two to correctly define the data of the software system. The model provides the necessary basis for deduction and conforms to the gradually refined thinking process of software engineering.
