基于模型驱动架构的GIS应用开发研究

模型驱动架构是一种通过用于定义模型和推动不同模型类型之间的转换实现系统与平台无关性的设计和实现方法。提出基于模型驱动架构进行GIS应用系统开发思想--用模型驱动的原理隔离GIS应用系统的系统设计和系统实现来独立建模业务行为和领域元素，使二次开发者关注系统应用的本身，而不是将特定的GIS基础平台作为系统开发的中心。并对通过建立领域应用模型和通用GIS服务模型来构建应用系统的平台无关模型、利用GIS平台提供的UML Profile将平台无关模型影射到平台相关模型、以及利用建模工具软件将平台相关模型生成应用代码的原理和方法进行了论述。

A Study of MDA-Based GIS Applied System Development

MDA is a new way of applied system analysis and design,which does not depend on infrastructure platforms,through defining models and driving transformation among models.The authors introduce a new GIS development method based on MDA.Using this method,developers can make modeling,model transaction behavior and elements of specific domain crossing different GIS platforms,and focus on application regardless of the characteristics of GIS platforms.The authors also presents principles and methods of building platform independent models through establishing domain models and general GIS models,and mapping platform independent model to platform specific model based on UML Profile,as well as the way of generating software codes from platform specific models using model developing tools.
