摘要
文中结合某市协同门户项目重点介绍了数据中心的技术原理、MVC(model-view-controller):模型层、视图层、控制层)架构、文件分组压缩打包技术,提出了广泛应用数据中心来实现经济、信息和社会效益增长的观点.本项目主要分为农业数据中心管理系统、农业信息发布系统、农业综合信息服务3个系统,实现从数据集成、共享服务接口发布到数据展示和提供标准共享服务接口等一系列系统功能的规划.建设农业信息数据中心,通过数据交换平台将各业务系统数据实时交换和同步到农业信息数据中心,实现各系统之间互联互通,满足农业部门及涉农部门纵向和横向数据采集和共享的需求.基于农业信息共享库建设农业信息发布系统,对数据进行业务建模、整理、分析,将分析结果和信息发布到综合信息服务门户上.建设农业综合信息服务门户,为某市农业部门提供农业信息资源的综合展现平台.本项目最终实现农业数据中心管理系统为核心,实现资源整合及集中管理,全面实现农业信息的共享与交换,为农业部门提供农业综合信息服务.本项目采用J2EE架构作为整体方案的技术框架,引入先进的组件化思想,减少各模块间的关联性,剥离业务属性,抽取功能属性,将耦合度降到最低,形成可独立存在的组件.符合国家电子政务相关标准与规范要求,充分保证农业部门行业特色和业务联动.基于统一规划的安全保障体系和统一的系统管理平台,满足对信息系统的管理要求与系统安全要求.
