地质灾害监测数据自适应对象持久化方法

摘要

为方便地质灾害监测数据管理系统中的数据操作,提出一种自适应对象持久化的方法.通过消息激励触发自适应对象生成机制,自动确定多态类型并定制所需临时持久化类型,以完成后续的对象持久化操作以及数据层和持久化层的交互操作.分析Java反射机制的原理,得出该方法在地质灾害监测数据管理系统中的实现过程,在实验环境下进行测试,分析响应速度和综合效率.实验结果表明,该方法能够方便地质灾害数据操作,减少程序冗余度,利于扩展和维护,提高地质灾害监测数据管理系统的应用开发效率,可推广至其它数据管理系统.%To simplify the operation of geohazard monitoring data management system,a method of adaptive object persistence was presented.The adaptive object generation mechanism was triggered by news motivation,the polymorphic type was determined and the required temporary persistence type was customized automatically.In this way,subsequent object persistence operation and interactive operation between data layer and persistence layer were completed.By analyzing the principle of Java reflection mechanism,the realization process of the method in geohazard monitoring data management system was concluded.At the same time,the realization of this method in geohazard monitoring data management system was obtained,and the test was carried out under the condition of experiment,and the response speed and the comprehensive efficiency were analyzed.The results show that the method can facilitate the operation of geological disaster data and reduce the redundancy of the program.The application and development efficiency of geohazard monitoring data management system is improved,which can be genera-lized to other systems.
