如何利用MySQL和Python開發一個簡單的線上招募系統
一、引言
隨著網路的普及和資訊化的發展,線上招募系統逐漸成為企業招募人才的首選方式。本文將介紹如何利用MySQL和Python開發一個簡單的線上招募系統。透過這個系統,企業可以發布招聘信息,求職者可以瀏覽職位並提交簡歷,同時系統還可以自動匹配職位和求職者,簡化招聘流程,提高效率。
二、系統需求
為了開發一個完整的線上招募系統,我們需要考慮以下幾個面向的功能:
三、資料庫設計
線上招募系統需要使用資料庫來儲存企業、求職者和職位等資訊。我們可以使用MySQL資料庫來建立以下幾個表格:
四、後端開發
使用Python中的MySQL連線庫,連接到MySQL資料庫,並建立對應的遊標對象。
import pymysql # 连接数据库 conn = pymysql.connect(host='localhost', user='root', password='password', database='recruitment_system') cursor = conn.cursor()
def register_company(company_name, email, password): sql = "INSERT INTO company (company_name, email, password) VALUES (%s, %s, %s)" cursor.execute(sql, (company_name, email, password)) conn.commit()
def login_company(email, password): sql = "SELECT company_name FROM company WHERE email=%s AND password=%s" cursor.execute(sql, (email, password)) result = cursor.fetchone() if result: return result[0] else: return None
def publish_position(company_name, position_name, description): sql = "INSERT INTO position (company_name, position_name, description) VALUES (%s, %s, %s)" cursor.execute(sql, (company_name, position_name, description)) conn.commit()
def register_applicant(name, email, password): sql = "INSERT INTO applicant (name, email, password) VALUES (%s, %s, %s)" cursor.execute(sql, (name, email, password)) conn.commit()
def login_applicant(email, password): sql = "SELECT name FROM applicant WHERE email=%s AND password=%s" cursor.execute(sql, (email, password)) result = cursor.fetchone() if result: return result[0] else: return None
def browse_positions(): sql = "SELECT position_id, position_name, description FROM position" cursor.execute(sql) positions = cursor.fetchall() return positions
def submit_resume(applicant_name, position_id): sql = "INSERT INTO resume (applicant_name, position_id) VALUES (%s, %s)" cursor.execute(sql, (applicant_name, position_id)) conn.commit()
def match_positions_and_applicants(): sql = "SELECT applicant_name, position_id FROM resume" cursor.execute(sql) resumes = cursor.fetchall() for resume in resumes: applicant_name = resume[0] position_id = resume[1] # 根据不同的匹配算法进行匹配,并将结果插入到推荐表(recommend)中
