2、此时便对权 限进行管理, 从而对安全性进行管理。 2.对后台数据库的维护和管理, 由于数据库有很多的表格, 而且几乎上都是相互关联的,所以对表的修改涉及到整个后台的数据体,必须做统一的考虑。 3.数据库的合理性要求能够对整个系统起到简化的作用,所以对库的规划必须合理。4.对于后台 的不断修改以及操作,必须要求数据库的稳定性。如对表格的修改能够准确的进行,且避免死锁 的现象。当对数据进行修改时,如进行删除,但此时数据正再用,必须要还原到正确的状态。要 不会影响以前的操作!对于系统的维护很难得到保证。 为解决这种情况必须要对数据库的操作进 行限制以及屏蔽,使用户尽量不要碰到此种情况。5.验证系统的
3、稳定性,对其进行检测。6.按照 模块化对成绩管理系统给出一个合理的解决方按。 【关键词】 模块 权限 数据库 后台 表格 ABSTRACT “ means revolution of information “ is turned to “ the content revolution of the information “, has caused the global digital campus to build tides .

4、hould be orientated as information service, designed starting point and final purpose to the high-efficient and accurate administrative system of students achievement, can meet the general demands of the student and teacher , as well as can be in order to manage to such authorities of confirming it
5、as users type , demand characteristic ,etc Demand not above-mentioned it provide one piece settlement that is reasonable and then according to,last respect not following mainly:1. Divide the whole system into two major module : The front desk and backstage supporter, among them the front desk is mai
6、nly design of the interface and relation of the interface, and the backstage supporter is mainly control over database and code. Primary demand for the database is rationality and security designed, manage authority at this moment , thus manage security . 2. To the maintenance and management of backstage supporters database, because the database has many forms , and it has to be interrelated all nearly, so his-and-hers watches is it involve whole datum body of backstage supporter to revise,
