基于UML的环境空间决策支持系统的分析与设计

统一建模语言(UML)是一种面向对象，定义明确的可视化系统建模语言，在地理信息系统工程的分析和设计中已逐渐被采用。以福建省海岸带环境调控空间决策支持系统为例，简述了系统建设背景和基本功能需求，研究了统一建模语言(UML)在空间决策支持系统分析和设计中的应用。重点提出了以系统需求用例图、活动图，类图和序列图为核心的UML辅助空间数据建模的基本原理和方法，并结合具体示例给出了基本操作流程过程和软件文档制品，最后给出了系统实现结果的典型用户界面。

UML-based analysis and design on environment spatial decision-making support system

The unified modeling language (UML) is an object-oriented and strictly defined visualizing data modeling language. It has been gradually adopted in analysis and design of GIS application engineering. The system construction background and main functional requirements are briefly introduced associated with coastal environment regulation spatial decision-making support system, and then a study on analysis and design of spatial is performed decision support system based on UML, taking the coastal environmental regulation spatial decision support system in Fujian Province as a case. The essential principle and methodology of spatial data modeling using use-case diagram, class diagram, activity diagram and sequence diagram are proposed, which are UML core components. And the related basal manipulation flows and software documents are presented associated with the prototype system. Finally, the typical user interfaces of the system realized application are illustrated.
