摘要
在校园一卡通系统中,为提高学生信息处理效率,使用数据关联工具管理学生信息,利用学生学号建立数据关联存储,在多张数据表间创建一个在逻辑对象关键属性值上有对应关系的物理数据子集,使数据检索速度加快,提高了校园一卡通系统工作效率。
In order to improve the processing efficiency of students information in the campus onecard system,the research suggests managing Students information with Data base associating tools,establishing data associating storage with student number,and creating a subset of physical data that has a corresponding relationship to the value of a logical object＇s key attribute between multiple data tables.Such an approach is able to speed up data retrieval and improve the work efficiency of campus one-card systems.
