基于GIS的矿产资源管理信息系统之需求分析模型建模方法

MODELING FOR REQUIREMENT ANALYSIS OF THE GIS-BASED MINERAL RESOURCES MANAGEMENT INFORMATION SYSTEM

在“基于GIS技术的矿产资源管理信息系统”开发过程中,运用软件工程原理建立了规范化的系统需求分析模型.使用系统分析的重要工具———数据流程图和数据字典对新系统逻辑模型(即工作流程)进行了规范化的精确描述.采用软件工程方法进行规范化的建模对矿产资源信息系统的开发具有重要意义.

During the development of ＂The GIS-based Mineral Resources Management Information System＂, the software engineering principle is adopted to establish the standardized system requirement analysis model. The logical model （work process） of the new system is accurately described with the data flow diagram （DFD） and data dictionary, which are the essential tools for systematic analysis. The method of software engineering in standardized modeling is significantly important for the development of mineral resources information system.
