地理国情基本统计算法模型管理策略研究

Management Strategy of Basic Statistical Models for National Geographic Conditions Monitoring

本文针对地理国情基本统计软件开发过程中算法复杂、需求变化快的特点,提出了一种基于反射机制的统计算法模型管理策略。通过算法模型库的管理,无需编译源程序就可以定制、修改和添加统计算法模型。主要思想是基于反射机制实现统计算法模型的整合,运用策略模式来实现统计对象与统计算法的解耦,并且通过配置文件方式描述和表达要素之间的关系,以及统计模块的属性配置。基于该策略实现了地理国情基本统计软件算法模型的有效管理,大大提高了软件的扩展性和灵活性。

Focusing on the complexity of algorithms and rapid change in the basic statistical system for geographic conditions census,this paper puts forward a management strategy of statistical models.The application framework realizes modifying and adding software functions by configuring the software independently without compiling the source code.The main idea is integrating the statistical algorithms model by reflection mechanism,using strategy pattern to decouple the statistical object model and statistical algorithms,and expressing the relationship between the elements and the statistics module configured by the configuration files.The strategy was applied into the system and was verified in the aspect of its effectiveness in improving software expansibility.
