计算机毕业设计??VB学生成绩管理系统论文?摘? 要 ?“信息手段革命”转向“信息内容革命”，引发了全球性数字校园建设浪潮。为满足为学校服务这一基本功能，数字校园应定位于信息服务，对学生的成绩的高效而准确的管理系统设计的出发点和最终目的，既要能够满足学生和老师的一般需求，又要能够针对用户的类型、需求特征等确定它的的权限以便进行管理。根据上述要求给出一个合理的解决方按，主要包括以下几个方面：1.将整个系统分为两大模块：前台与后台，其中前台主要是界面的设计以及界面的关联，而后台主要是对数据库的管理以及编码。数据库的首要要求便是设计的合理性以及安全性，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 . This basic function of serving school for being satisfied , the digital campus should 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 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 mainly 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, must do unified consideration . 3.
