南水北调中线干线工程移民环保管理系统设计与性能优化

通过分析南水北调中线干线工程建设管理中移民环保的业务特点及功能要求，设计出一套基于南水北调中线干线工程建设管理信息系统的移民环保管理子系统，符合南水北调中线干线工程建设管理信息系统开发的整体流程及规范。讨论了当前开发大型管理系统的设计模式及体系结构，综合比较各种体系及框架，综合考虑系统结构、开发周期以及代码重用等方面，采用先进的J2EE技术B／S模式，采用基于MVC设计模式的Struts框架及数据持久化层的Hibernate框架，并对原型系统性能进行了测试，作出了深入的探讨与分析，且给出优化原型系统的方法，包括客户端与服务器端的交互问题、大量数据统计查询的性能问题等。本系统的实现将为我国大型工程建设管理的信息化起到示范作用。

Design and Optimization of the Migration Management System in the South-to-North Water Transfer

By analyzing the migration environmental characteristics,we designed a set of migration environmental management subsystem in the South-to-North Water Transfer Management Information System.The paper discusses design patterns and architecture of a large-scale management system and has comprehensive comparison of different systems and frameworks,decides to adopt the J2EE technology B/S mode based on the MVC design pattern struts framework and data persistence layer of Hibernate framework.Furthermore,the system performance test and optimization method are given including client and server interaction,large statistical data query performance issues and the development and maintenance of pages.The system will play an exemplary role for large-scale construction projects in China's information management.
