学籍管理系统摘要学籍管理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。对于前者要求建立起数据一致性和完整性强、数据安全性好的库。而对于后者则要求应用程序功能完备,易使用等特点。本系统主要完成对学生情况和学生成绩的管理,包括数据库中表的添加、修改、删除等。系统还可以完成对各类信息的浏览、查询、添加、删除、修改、报表等功能。系统的核心是数据库中各个表联系,每一个表的修改都将联动的影响其它的表,当完成对数据的操作时系统会自动地完成数据库的修改。查询功能也是系统的核心之一,在系统中即有单条件查询和多条件查询,也有精确查询和模糊查询,系统不仅有静态的条件查询,也有动态生成的条件查询,其目的都是为了方便用户使用。系统有完整的用户添加、删除和密码修改功能,并具备报表打印功能。经过分析,我们使用MICROSOFT公司的VISUALBASIC开发工具,利用其提供的各种面向对象的开发工具,尤其是数据窗口这一能方便而简洁操纵数据库的智能化对象,首先在短时间内建立系统应用原型,然后,对初始原型系统进行需求迭代,不断修正和改进,直到形成用户满意的可行系统。关键字管理信息系统、数据库、vb6.0、access2000。ABSTRACTStudentstatusmanagementsystemisdevelopmenttwoaspectsthattypicalinformationmanagementsystem,IMSMIS,itsdevelopmentincludesprimarilythebackgrounddatabasecreateswithsupportandthefrontendappliestheprocedure.Createstorisetotheformerrequesttheconsistencyofdataisstrongwiththeintegrity,thelibrarythatthesafenessofdatalike.Butrequestthelatterverymuchtoapplytheprocedurefunctioncomplete,easyusageetc.characteristics.Thissystemcompletesprimarilytostudentscircumstancewiththemanagementofstudentsscore,includethedatabasetheinsidethewatchincrease,modify,deleteetc..Thesystemcanalsocompletetothebrowsingofvariousinformation,search,increase,delete,modify,reportetc.function.Systemofnucleusisothertableinaninfluenceforofrelation,eachamodificationofwatchmovinginatableindatabasethatmodificationthatoperationhoursystem,betocompletethelogarithmsaccordingtowillcompletethedatabaseofoneself.Searchthefunctionisalsooneofthenucleusofthesystem,havingnamelyinsystemthesingleconditionsearchtosearchwithmanyconditions,alsohavingtheaccuratesearchtosearchwithblur,systemnotonlycontainstaticconditionsearch,alsohavethedynamicbornconditionsearch,itspurposeisallforthesakeoftheconvenientconsumertouse.Systemcontaincompleteconsumerincrease,deletetomodifythefunctionwiththepassword,theunionhasthereportprintsthefunction.Throughanalysis,weusetheMICROSOFTcompanyVISUALBASICdevelopmenttool,makinguseofitseverykindofthetoolofdevelopmentthatprovidethatfacetotheobject,particularlyisintelligencethatthewindowofdatathisoncanningbeconvenientbutmanipulatethedatabaseinbrieftoturntheobject,createintheinashorttimefirstsystemapplicationprototype,then,starttothebeginningtheprototypesystemproceedstorequirewiththeiteration,revisingcontinuouslywithimprove,untilformingtheconsumerissatisfiedcanrowsystem.KeywordsMIS,database,vb6.0,access2000.目录前言..............................................................................................................................1第一章概述..................................................................................................................11.1课题来源.............................................................................................................11.2开发工具的选用................................................................................................21.2.1VisualBasic的使用.................................................................................21.2.2MicrosoftAccess的使用..........................................................................31.3系统的初步调查................................................................................................31.4系统的可行性研究...........................................................................................41.4.1技术上的可行性.......................................................................................41.4.2管理上的可行性.......................................................................................41.4.3安全上的可行性.......................................................................................41.5系统分析............................................................................................................41.5.1系统的安全性...........................................................................................41.5.2系统的快捷性...........................................................................................51.5.3系统的准确性...........................................................................................51.5.4系统的严谨性...........................................................................................5第二章概要设计..........................................................................................................52.1系统设计思路....................................................................................................52.1.1界面设计...................................................................................................52.1.2用户登陆...................................................................................................52.1.3学籍信息内容查询和录入.......................................................................62.1.4数据库分析...............................................................................................62.2设计简述............................................................................................................62.2.1vb设计的界面简述..................................................................................62.2.2Access2000设计数据库..........................................................................72.2.3系统简图....
