使用Python打造个人简历系统：基于MySQL数据库的完美方案

想要高效管理个人简历信息？本文将带您使用Python和MySQL数据库，一步步构建功能完备的个人简历系统。

一、数据库设计：构建简历信息的数据仓库

首先，我们需要设计数据库表结构，用于存储简历的各个方面信息。我们使用MySQL数据库，创建以下五个数据表：

1. personal_info (个人信息表) - id: INT PRIMARY KEY AUTO_INCREMENT (主键，自增) - name: VARCHAR(255) (姓名) - gender: VARCHAR(10) (性别) - birthdate: DATE (出生日期) - id_number: VARCHAR(20) (身份证号) - phone: VARCHAR(20) (电话) - email: VARCHAR(255) (邮箱)

2. education_info (教育经历表) - id: INT PRIMARY KEY AUTO_INCREMENT (主键，自增) - person_id: INT (外键，关联personal_info表的id字段) - school: VARCHAR(255) (学校) - major: VARCHAR(255) (专业) - degree: VARCHAR(255) (学历) - start_date: DATE (开始日期) - end_date: DATE (结束日期)

3. work_info (工作经历表) - id: INT PRIMARY KEY AUTO_INCREMENT (主键，自增) - person_id: INT (外键，关联personal_info表的id字段) - company: VARCHAR(255) (公司) - position: VARCHAR(255) (职位) - start_date: DATE (开始日期) - end_date: DATE (结束日期)

4. project_info (项目经历表) - id: INT PRIMARY KEY AUTO_INCREMENT (主键，自增) - person_id: INT (外键，关联personal_info表的id字段) - name: VARCHAR(255) (项目名称) - description: TEXT (项目描述) - start_date: DATE (开始日期) - end_date: DATE (结束日期)

5. skill_info (技能信息表) - id: INT PRIMARY KEY AUTO_INCREMENT (主键，自增) - person_id: INT (外键，关联personal_info表的id字段) - name: VARCHAR(255) (技能名称) - level: VARCHAR(255) (技能水平)

二、Python代码实现：让简历数据动起来

接下来，我们使用Python语言和pymysql库连接MySQL数据库，并编写代码实现简历信息的增删改查功能。

**1. 安装必要库：**bashpip install pymysql

**2. Python代码示例：**pythonimport pymysql

连接到MySQL数据库conn = pymysql.connect(host='localhost', user='root', password='your_password', database='resume_db')cursor = conn.cursor()

插入个人信息数据sql = 'INSERT INTO personal_info(name, gender, birthdate, id_number, phone, email) VALUES (%s, %s, %s, %s, %s, %s)'values = ('张三', '男', '1990-01-01', '110101199001011234', '13800138000', 'zhangsan@example.com')cursor.execute(sql, values)conn.commit()

获取最新插入的记录的id值person_id = cursor.lastrowid

插入教育经历数据sql = 'INSERT INTO education_info(person_id, school, major, degree, start_date, end_date) VALUES (%s, %s, %s, %s, %s, %s)'values = (person_id, '清华大学', '计算机科学与技术', '本科', '2010-09-01', '2014-06-30')cursor.execute(sql, values)conn.commit()

... 插入其他信息（工作经历、项目经历、技能信息）

查询个人信息及其相关经历和技能信息sql = '''SELECT pi.name, pi.gender, pi.birthdate, pi.id_number, pi.phone, pi.email, ei.school, ei.major, ei.degree, ei.start_date AS edu_start_date, ei.end_date AS edu_end_date, wi.company, wi.position, wi.start_date AS work_start_date, wi.end_date AS work_end_date, pri.name AS project_name, pri.description AS project_description, pri.start_date AS project_start_date, pri.end_date AS project_end_date, si.name AS skill_name, si.level AS skill_levelFROM personal_info piLEFT JOIN education_info ei ON pi.id = ei.person_idLEFT JOIN work_info wi ON pi.id = wi.person_idLEFT JOIN project_info pri ON pi.id = pri.person_idLEFT JOIN skill_info si ON pi.id = si.person_idWHERE pi.id = %s'''cursor.execute(sql, person_id)result = cursor.fetchone()print(result)

关闭数据库连接cursor.close()conn.close()
