基于UML的数字测绘产品质量检验软件DXF功能组件的设计

统一建模语言(UML)是一种绘制软件蓝图的标准语言1],是软件工程环境中对象分析和设计的重要工具,用于对软件进行描述、可视化处理、构造和建立软件系统的文档2]。而组件技术的蓬勃发展使基于组件组装的软件开发成为可能,两者正无可争议地成为当今和未来软件开发的主流技术。本文以数字测绘产品质量检验软件中基于DXF数据操纵的功能组件为例,在分析用户需求和DXF数据的基本特征的基础上,讨论了运用UML对该组件进行面向对象建模的方法和分析设计过程,最后展示了实现后的组件系统结构和功能。

DXF component design for quality inspection software for digital surveying and mapping products based on UML

UML is a graphical language for visualizing,specifying,constructing,and documenting the artifacts of a software-intensive system.It is the important tool to analysis and design in software engineering,while the development of component technology has made it feasible to build applications by assembling the off-the-shell components.These two,with no doubt,are going to be the mainstream of software development technologies in the near future.The paper will carry out the requirement analysis for DXF Component of Quality Inspection Software for Digital Surveying and Mapping Products,and then complete analysis and design the model of DXF component with UML through the idea of object-oriented method.At last the system structure and functions of DXF component that has been accomplished are discribed.
