Python鏈接SqlServer+GUI嵌入式——學生管理系統1.0

學生管理系統1.0html

1.建學生數據庫python

2.數據庫嵌入高級語言（Python）sql

3.界面設計數據庫

簡化思路：服務器

1.先經過SqlServer2012創建學生數據庫，包括帳號、密碼，姓名、選課等信息框架

2.運用Python的pymssql庫與SqlServer創建鏈接再用tkinter庫建立GUI界面ide

1）SqlServer建學生數據庫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）在學生庫內建表並插入數據佈局

 1 create table Students  2 (學號 char(10) primary key,  3 密碼 varchar(20) not null,  4 姓名 char(20) not null,  5 性別 char(5),  6 出生日期 date  7 )  8  9 create table Course 10 (課程名 char(30) not null, 11 課程老師 char(20) not null, 12 課程號 char(10) primary key) 13 14 create table Report 15 (學號 char(10), 16 課程號 char(10), 17 成績 int, 18 primary key(學號,課程號), 19 constraint Students_Report foreign key(學號) references Students, 20 constraint Couse_Report foreign key(課程號) references Course) 21 22 23 insert 24 into Students 25 values 26 ('2018165201','12345678','李銘','男','2000-02-01'), 27 ('2018165202','12345678','劉曉鳴','男','2000-08-02'), 28 ('2018165203','12345678','李明','男','1999-07-09'), 29 ('2018165204','12345678','張鷹','女','1998-08-20'), 30 ('2018165205','12345678','劉竟靜','女','1999-09-09'), 31 ('2018165206','12345678','劉成剛','男','2000-10-10'), 32 ('2018165207','12345678','王銘','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 ('數據庫', '美美', '20185101'), 39 ('機率論', '楊曉東', '20185102'), 40 ('C語言', '黃曉明', '20185103'), 41 ('計算機基礎', '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')

效果圖：

1)登陸界面

2）功能選擇

3）成績查詢

4）密碼修改

缺點：1.功能較少，僅查詢成績與修改我的密碼。

　　　2.界面設計較簡陋。

　　 3.數據模式設計還不夠完整合理

說明：主要運用Python的pymssql和tkinter庫和類定義等方法作出這個嵌入式做業，將於空閒時間繼續改進，設計出更合理的數據關係模式。
