软件工程课程设计---学生信息管理系统

软件工程课程设计---学生信息管理系统n1.1 BackgroundWith the XXX。

XXX in size and the number of students and their n is increasing rapidly。

us n management systems for students have emerged to manage student n and improve the efficiency of system management work。

The student n management system combines Eclipse (front-end development) with SQL database (back-end management) and XXX standardized management。

scientific statistics。

and fast queries of student n。

which greatly ces the workload of management.The database plays a very important role in an n management system。

The quality of database structure design XXX of the n system。

Reasonable database structure design can improve the efficiency of database storage。

XXX。

At the same time。

reasonable data structure will also be XXX.1.2 XXX DevelopmentThis system uses Eclipse development tool as the development system program and SQLsever database access XXX query of database n。

SQLsever uses a simpler and more flexible object model。

which is XXX the following n methods:1) Connect to the data source.2) Specify the command to access the data source。

and parameters XXX.3) Execute the command。

such as a SELECT statement.4) In appropriate circumstances。

changes to cached rows can be written back to the database to update the data source.5) Provide routine methods to detect errors。

which are usually XXX。

and involve SQL error objects.2 System Analysis2.1 XXXUsers must register an account and password before they can manage and use the system。

Otherwise。

they need to register a new account before logging in to the system。

Administrators can perform us ns on the database data by entering their password and account。

while ordinary users can only perform some ns。

Users can select the corresponding XXX the n they need.1) The ns of the student n management system are to display the main n page。

log in through password n。

and handle file n。

By logging in through password n。

secure and reliable login can be achieved。

The student n processing n includes inputting student n。

displaying student file n。

student file n nal query (divided into: query by student name。

query by student ID)。

and XXX.2) The nal modules of the student n management system include:该学生信息管理系统的登陆界面设计美观大方，用户只需按下enter键即可进入密码验证登陆界面。

输入正确密码后，用户将进入主菜单选择框架界面，方便用户对程序各个功能进行选择。

用户只需按下enter键即可进入所需功能。

该系统分为多个小模块，通过调用实现各种功能，增强了程序的可建设性。

业务需求包括安全性、权限分配和易操作性。

用户必须通过帐号和密码才能进行对该系统的管理。

超级管理员通过输入密码和帐号可以对数据库的数据进行各种操作，而普通用户仅仅可以进行一部分的操作。

系统易于操作，能够快速进行查询操作，进行数据的汇总。

为了满足用户对各种信息的提供、保存、更新、查询和统计等需求，数据库结构应充分满足各种信息的输入和输出。

系统应定义数据结构、收集基本数据以及设置数据处理的流程，组成一份详尽的数据字典，为以后的具体设计打下基础与伏笔。

在仔细分析、调查有关学生信息管理需要的基础上，得到了本系统的流程图。

总体设计流程图包括密码登陆界面、登陆主菜单选择框架界面、输入信息模块、显示信息模块、条件查询模块、更新信息模块和退出系统模块。

用户可以根据自己的需求方便快捷地做出选择。

密码登陆函数流程图和选择框架函数流程图分别描述了密码登陆和选择功能的具体流程。

Upon entering the student record management system。

the program name and main menu n frame will be displayed。

prompting the user to select and complete the corresponding task。

This code is called by the main() n.Input n n Flowchart:System starts input processEnter student IDEnter nameEnter genderInput errorRetry inputEnter contact nEnter classThe input n n module allows users to follow the prompts and input n step by step。

When input is incorrect。

the system willXXX the user to correct it。

In this system。

users are required to input only character and numeric data。

and corresponding XXX.Display n Flowchart:Display nn startsOutput student nEndWhen the user enters the n query module。

the system will display the XXX.Query n Flowchart:Select query n to startSelect to query by name or IDQuery by nameInput errorOutput nRetry inputOutput nQuery by IDWhen the user performs this query task。

the system will remind the user to select the query field。

that is。

to query by IDor name。

If the student record n exists。

the record n will be displayed。

This n completes the node n n.Update n Flowchart:Update n n startsRetry inputEnter the student ID to be updatedInput errorEnter the updated n and retry input if error occursOutput updated nCompleteIn the n of updating student record n。

the system will first query the student record n based on the input student ID。

and then fill in the modified student n in order.System Design:3.1 System n Structure DiagramWhen designing a database system。

it should fully meet the input and output of us n。

Based on this。

the main tasks that thestudent n management system XXX。

The main tasks of the student n management system are as follows:1) Input of basic n。

This includes the input of enrollment (student basic) n。
