成绩查询系统是典型的信息管理系统(MIS),其开发主要包括后台数据库的建立和维护以及前端应用程序的开发两个方面.对于前者要求建立数据一致性和完整性强,数据安全性好的数据库.而对于后者则要求应用程序功能完备,易使用等特点。成绩查询都是依赖人工进行的,面对如此众多的成绩信息,其工作量可想而知,不仅仅浪费了大量的人力物力,而且由于人工管理存在着大量的不可控因素,造成了不必要的浪费。 [来源:http://think58.com]

Abstract [资料来源:www.THINK58.com]

System performance is a typical management information system (MIS), including the development of its background of the establishment and maintenance of the database front-end applications, as well as the development of both. The former calls for the establishment of strong data consistency and integrity, good data security Database. For the latter applications require full-featured and easy to use and so on. Query results are dependent on the manual, in the face of so many accomplishments, its workload would be, as not only a waste of a great deal of manpower and material resources, but also because of artificial management exists a large number of uncontrollable factors, resulting in unnecessary Waste.
