基于MVC模式的三峡通航数据维护系统的实现

三峡-葛洲坝联合调度系统是保证葛洲坝和三峡船闸调度顺利进行的关键,系统要求有较好的安全性、实时性和分布式结构。针对系统性能要求,采用Hibernate2,WebWork2.1等多种技术,设计并在J2EE平台实现了一个采用MVC模式的三峡船闸调度系统中的通航数据维护系统。这种设计模式使系统结构层次清晰,各部分模块划分明确。文中还用系统中的实例介绍了Hibernate映射Oracle关系数据库、DAO模式实现对数据模型的透明访问等关键技术。实际应用证明采用B/S模式更能适应联合调度系统的数据维护需要,数据完整性和实时性都得到了良好的保证。

Implementation of Data Maintenance of Three Gorges Scheduling System Based on MVC Pattern

Three Gorges scheduling system is crucial to the ship arrangement of the dam,which requires good safety,realtime quality and distribution structure.This paper describes how to construct the data maintenance sub-system of Three Gorges scheduling system by using MVC pattern based on J2EE platform.This pattern makes the structure clear and every division has its definite function.The paper also represents OR Mapping Oracle database by Hibernate,DAO pattern and other key technologies with actual applications in the system.Pratical applications have proved that the B/S pattern could satisfy the reqirements better.Both integrity and realtime quality of the data have been improved.
