摘要
针对船舶管理系统网络特点及其独特的分布式数据库同步需求,分析船岸数据同步更新机制,以数据同步组件方式,从数据采集、网络数据交互模型、数据缓存、数据同步流程等方面设计和实现船岸数据同步。通过软件技术解决数据同步的可靠性问题,为船舶管理系统的数据同步提出可行的解决方案。
According to network architecture features of ship management system and its unique requirements of distributed database synchronization,the ship-to-shore data synchronization update mechanism is researched. By means of data synchronization components,the ship-to-shore data synchronization is designed and realized in aspects of the data acquisition,network data interaction model,data caching and data synchronization process. The reliability of data synchronization is ensured by software technology,offering feasible solutions to the data synchronization of ship management system.
