| 摘 要： | 随着GIS在农业领域应用的不断深入,农业GIS应用系统的开发也朝着具体、复杂和专业化方向发展。针对目前农业GIS应用系统开发中存在的概念模型、数据模型、元数据标准不统一、数据库整合性差等不足,本文通过分析MDA架构体系及开发流程,结合软件复用思想和MDA方法,提出一种基于MDA的农业GIS应用系统开发构建方式,阐述了空间数据库模型建设等一些关键技术。结合实例,探讨了MDA方法在农业GIS应用系统构成过程中的可行性与优越性以及不足之处。

| Abstract: | With the deeply application of GIS in agricultural sector,the development of agriculture GIS application system is moving in the specific,complex and specialized.Aiming at the existed shortages of the current agricultural GIS application system,such as lack of unification among conceptual model,data model,metadata standards,limitation of database integration,by analyzing the MDA framework and development process,combined with software reuse ideas and the MDA approach,this paper proposed a MDA-based development mode for building agricultural GIS applications,and described some key technologies for spatial database model construction.With examples,it also discussed the feasibility,advantages and disadvantages in constructing agricultural GIS application system based on MDA method. |
