Python链接SqlServer+GUI嵌入式——学生管理系统1.0

学生管理系统1.0html

1.建学生数据库python

2.数据库嵌入高级语言（Python）sql

3.界面设计数据库

简化思路：服务器

1.先经过SqlServer2012创建学生数据库，包括帐号、密码，姓名、选课等信息框架

2.运用Python的pymssql库与SqlServer创建链接再用tkinter库建立GUI界面ide

1）SqlServer建学生数据库oop

 1 create database student_Mis  2 on  3 (name = student_Data,  4 filename='F:\SQL list\student_mis_data.mdf',  5 size = 20,  6 maxsize = 100,  7 filegrowth = 10)  8 log on  9 (name = student_Log, 10 filename = 'F:\SQL list\student_mis_log.ldf', 11 size = 5mb, 12 maxsize = 50mb, 13 filegrowth = 5mb)

2）在学生库内建表并插入数据布局

 1 create table Students  2 (学号 char(10) primary key,  3 密码 varchar(20) not null,  4 姓名 char(20) not null,  5 性别 char(5),  6 出生日期 date  7 )  8  9 create table Course 10 (课程名 char(30) not null, 11 课程老师 char(20) not null, 12 课程号 char(10) primary key) 13 14 create table Report 15 (学号 char(10), 16 课程号 char(10), 17 成绩 int, 18 primary key(学号,课程号), 19 constraint Students_Report foreign key(学号) references Students, 20 constraint Couse_Report foreign key(课程号) references Course) 21 22 23 insert 24 into Students 25 values 26 ('2018165201','12345678','李铭','男','2000-02-01'), 27 ('2018165202','12345678','刘晓鸣','男','2000-08-02'), 28 ('2018165203','12345678','李明','男','1999-07-09'), 29 ('2018165204','12345678','张鹰','女','1998-08-20'), 30 ('2018165205','12345678','刘竟静','女','1999-09-09'), 31 ('2018165206','12345678','刘成刚','男','2000-10-10'), 32 ('2018165207','12345678','王铭','男','2000-01-01'), 33 ('2018165118','12345678','右耳朵耗子','男','1998-08-25') 34 35 insert 36 into Course 37 values 38 ('数据库', '美美', '20185101'), 39 ('几率论', '杨晓东', '20185102'), 40 ('C语言', '黄晓明', '20185103'), 41 ('计算机基础', '徐明', '20185104') 42 43 insert 44 into Report 45 values 46 ('2018165201','20185101', '90'), 47 ('2018165201','20185102', '80'), 48 ('2018165201','20185103', '99'), 49 ('2018165201','20185104', '88'), 50 51 ('2018165202','20185101', '70'), 52 ('2018165202','20185102', '90'), 53 ('2018165202','20185103', '90'), 54 ('2018165202','20185104', '78'), 55 56 ('2018165203','20185101', '89'), 57 ('2018165203','20185102', '85'), 58 ('2018165203','20185103', '90'), 59 ('2018165203','20185104', '67'), 60 61 ('2018165204','20185101', '88'), 62 ('2018165204','20185102', '85'), 63 ('2018165204','20185103', '85'), 64 ('2018165204','20185104', '85'), 65 66 ('2018165205','20185101', '90'), 67 ('2018165205','20185102', '90'), 68 ('2018165205','20185103', '90'), 69 ('2018165205','20185104', '90'), 70 71 ('2018165206','20185101', '0'), 72 ('2018165206','20185102', '0'), 73 ('2018165206','20185103', '0'), 74 ('2018165206','20185104', '0'), 75 76 ('2018165207','20185101', '0'), 77 ('2018165207','20185102', '0'), 78 ('2018165207','20185103', '0'), 79 ('2018165207','20185104', '0'), 80 ('2018165118','20185101', '100'), 81 ('2018165118','20185102', '100'), 82 ('2018165118','20185103', '100'), 83 ('2018165118','20185104', '100')

效果图：

1)登陆界面

2）功能选择

3）成绩查询

4）密码修改

缺点：1.功能较少，仅查询成绩与修改我的密码。

　　　2.界面设计较简陋。

　　 3.数据模式设计还不够完整合理

说明：主要运用Python的pymssql和tkinter库和类定义等方法作出这个嵌入式做业，将于空闲时间继续改进，设计出更合理的数据关系模式。
