基于Web的作物模型库系统构建

摘要

In order to suit the demand for both crop model development and application for information system, the structure for crop model base was analyzed. A software architecture for Web-based crop model base (WCMBS) was put forward, which includes crop model base (CMB), model base management system (MBMS) and system interface (SI). The system was developed with three-layer B/S architecture by using Asp.net+ XML, and the database was SQL Server2005. In order to achieve the transfer of the parameters in different models, the model description document based on XML was used to describe the model parameters. The system has the advantages of easy to use, Web-based and high reusability.%为满足作物模型开发和信息管理系统应用两方面的应用需求,对作物模型库系统结构进行了分析,提出了一种基于Web的作物模型库系统(WCMBS)的软件体系结构.WCMBS主要由作物模型库(CMB)、模型库管理系统(MBMS)、系统接口(SI)组成.系统采用3层B/S软件体系结构,利用ASP.net+XML开发语言,基于SQL Server2005数据库平台进行开发.采用基于XML的模型描述文档进行模型参数的描述,实现了不同模型描述语言之间的参数传递.系统具有简单易用,完全面向Web、高可重用性的优点.
