Student Grade Management System

# Introduction

In this project, you will learn how to create a student information management system using MySQL. This system includes two tables: `student_info` and `student_score`, with a foreign key relationship between them.

## 👀 Preview

MySQL [studentSys]> DESC student_info;
+-------+-------------+------+-----+---------+----------------+
| Field | Type        | Null | Key | Default | Extra          |
+-------+-------------+------+-----+---------+----------------+
| Id    | int         | NO   | PRI | NULL    | auto_increment |
| name  | varchar(10) | YES  |     | NULL    |                |
+-------+-------------+------+-----+---------+----------------+
2 rows in set (0.002 sec)

MySQL [studentSys]> DESC student_score;
+-------+------------+------+-----+---------+-------+
| Field | Type       | Null | Key | Default | Extra |
+-------+------------+------+-----+---------+-------+
| Id    | int        | NO   | PRI | NULL    |       |
| score | varchar(4) | YES  |     | NULL    |       |
| Sid   | int        | YES  | MUL | NULL    |       |
+-------+------------+------+-----+---------+-------+
3 rows in set (0.001 sec)
