关于航班信息系统设计及实现的报告

一、选题

  1. 本实验选用国内某机场一天的航班数据作为基础数据，并在此基础上对数据进行增、删、查、改；
  2. 前端使用HTML语言、JavaScript、CSS语言，后端使用PHP语言
  3. 数据库使用MySQL

二、DB设计

  1. 数据库名db_work

  2. 使用单表操作

  3. 表名flights

  4. 表flights包含columns有：id,flight,source,destination,transit,arrival_time,terminal,status共8列

  5. 建立数据库即表的命令如下

    DROP DATABASE IF EXISTS db_work;
CREATE database db_work;
USE db_work;
SET names utf8;
CREATE TABLE flights
		(
		id int(3) NOT NULL AUTO_INCREMENT,
		flight char(6) NOT NULL,
		source tinytext NOT NULL,
		destination tinytext NOT NULL,
		transit tinytext,
		arrival_time time not null,
		terminal char(2) not null,
		status tinytext not null,
		PRIMARY KEY (id)
		)default charset=utf8;
INSERT INTO flights (flight,source,destination,transit,arrival_time,terminal,status) values ('8L9616','济南','成都','','0:00','T2','计划00:00到达');
INSERT INTO flights (flight,source,destination,transit,arrival_time,terminal,status) values ('MU5415','上海虹桥','成都','','0:05','T2','已于00:09到达');
INSERT INTO flights (flight,source,destination,transit,arrival_time,terminal,status) values ('3U5016','上海虹桥','成都','','0:05','T2','已于00:09到达');

三、实现

  1. 增加数据的功能由insert.html,insert.php两个文件共同实现；
  2. 删除数据的功能由delete.html,delete1.php,delete.2.php共同实现；
  3. 查询数据的功能由select.html,select.php共同实现；
  4. 修改数据的功能由alter.html,alter1.php,alter2.php,alter3.php共同实现
  5. 首页由index.php呈现
  6. 数据库连接由sql-connect.php实现

index.php
