摘要
目前海军装备测试记录的存储大多采用文本文件的形式,不利于数据共享。为解决这一问题,改进原先的存储方法,提出了数据库存储形式,讨论了其开发步骤,并针对应用背景,重点提出了通过现有存储方式的设计文档及相关代码获取设计的需求分析、通过模式分解将测试项目进行划分、通过数据依赖公理验证分解前后是否等价的数据库设计方法,最后通过一个实例对数据库应用系统的开发过程进行了详细说明。与文本文件存储方法相比,数据库存储形式具有利于数据共享、提高数据查询效率、便于装备管理的优点。
The storage scheme of equipment test records is mostly text file type at present,and it makes against data-sharing.In order to resolve this problem,we have to improve the original scheme,and we bring forward database scheme.This paper introduces its design process.Concerning application background,the paper introduces the method of getting requirement analysis via original design documents and program codes,and the method of dividing test items via pattern segmentation and of verification pattern segmentation via data dependence axiom.Finally,the paper gives a example to introduce the process of developing database application system in detail.Compared with text file type,database is convenient to data-sharing and improve query efficiency and equipments management.
