第2关：从需求分析到逻辑模型

任务描述

本关任务： 根据应用场景业务需求描述，完成ER图，并转换成关系模式。 提交设计文档

sql 复制代码 
请给出ER图文件存放的URL:
https://s1.wzznft.com/i/2023/12/01/ersolution.png
 以下给出关系模式：

电影(movie)(movie_ID, title, type, runtime, release_date, director, starring), 主码:(movie_ID)

顾客(customer)(c_ID, name, phone), 主码:(c_ID)

放映厅(hall)(hall_ID, mode, capacity, location), 主码:(hall_ID)

排场(schedule)(schedule_ID, date, time, price, number, hall_ID, movie_ID), 主码:(schedule_ID)，外码：(hall_ID) 参照放映厅(hall)，(movie_ID) 参照电影(movie)

电影票(ticket)(ticket_ID, seat_num, c_ID, schedule_ID), 主码:(ticket_ID)，外码：(c_ID) 参照顾客(customer)，(schedule_ID) 参照排场(schedule)
