一种基于参数字典的动态数据库设计与管理方法

摘要

In order to input the different weapon models with different parameters into a resource database for weapon experiment, a new method of dynamic database design based on parameter dictionary is proposed. The method which realized dynamic structure by taking the advantages of parameter structure datasheet, parameter dictionary datasheet and numerical datasheet satisfactorily solved the problem that the way of increasing datasheet couldn't realize dynamic database under SSH2 framework of J2EE platform. Because the principle of few times but large numbers must be considered in update of parameter dictionary, three parameter dictionary updating modes (parameter dictionary template leading-in mode and browser immediate input mode and worksheet leading-in mode) are put forward in database management. The system verification indicates that the method satisfied the requirement perfectly.%某武器试验资源库系统中,针对拥有不同参数数据的武器型号入库问题,提出了一种基于参数字典的动态数据库设计方法.该方法通过参数结构表、参数字典表、数值数据表实现动态结构,较好地解决了J2EE平台下SSH2不能通过增加数据表的方式实现动态数据库的问题.在动态数据库的管理中,针对参数字典更新的“少次、大量”的原则,提出并实现了3种参数字典更新模式:参数字典模板导入模式、浏览器端直接输入模式、工作表导入模式.经系统验证,很好地满足了要求.
