【摘要】 通过适当增加数据冗余,降低数据的复杂逻辑关系,可以减少程序量,从而提高系统的运行效率。结合具体问题中的实体关系的分析,通过实体关系分解,增加数据冗余,最终降低了程序运行所占用的资源,提高了系统运行的效率。更多还原

【Abstract】 Increasing data redundancy properly and decreasing the sophistic logic relation will reduce the programs so as to improve the system running efficiency.After analyzing the entity relation in the practical problem,this paper resolve the entity relation and increase data redundancy,and finally decreases the resource used in program running and improves the system running efficiency.更多还原
