军用电子设备试验数据库概念模型设计

摘要

从分析军用电子设备试验数据的特点入手,研究设计了试验数据库概念模型,提出了一种采用时间、设备和试验题目为关联条件对试验数据进行有效组织的三维关联数据模型,并将试验数据文件级管理和表级管理有机结合.实践表明,该概念模型能够满足试验数据管理系统的应用需求.%Starting from analyzing characteristic of military electronic equipment test data, the database conceptual model of military e-lectronic equipment test is designed. The three-dimensional relation data model which effectively organizes the test data using time, equipment and test subject as related conditions is proposed. The model combines the file-level management and table-level management of test data. Practice shows that the data model can meet the application requirements of the test data management system.
