MySQL數據庫大作業——學生管理系統GUI
原程序鏈接: https://www.bbsmax.com/A/kmzL3WQBdG/
為了完成數據庫大作業, 我在其基礎上進行了一定的修改和擴充.
如果要使用的話, 請修改__init__中的數據庫登錄信息，把其中的*****修改成自己的信息即可。
主界面會自動分辨學生與教工賬號，直接登錄即可。
使用程序之前
數據庫中表的建立：
# student
create table student(
sno char(8) primary key,
sname char(8) not null,
sex char(2),
birthday date,
tel varchar(20)
# student_course
create table student_course(
sno char(8) not null,
tcid smallint not null,
score tinyint)
# course
create table course(
cno char(10) primary key,
cname char(20) not null,
credit tinyint not null)
# teacher
create table student(
sno char(8) primary key,
sname char(8) not null,
sex char(2),
birthday date,
tel varchar(20))
# student_pwd
create table student_pwd(
user char(8) primary key,
pwd varchar(40) not null)
# teacher_pwd
create table teacher_pwd(
user char(8) primary key,
pwd varchar(40) not null)
重要！！
使用程序之前，請先使用MySQL創建一個teacher賬號。
需要同時在teacher表、teacher_pwd表中鍵入信息。
（pwd表中的user即為教工工號或學生學號）
