如何根据航班日期计算每天的费用（成本酒店+成本航班）？

我需要建立数据库设计关系来计算埃及游客的每次旅行费用。根据航班日期每人每天的飞行费用+酒店费用（客房费用+服务费）

假设我在阿姆斯特丹到埃及的航班日期为2017年6月23日

2017年6月26日从开罗到阿姆斯特丹将返回

所以计算如下：

Table tour
1   Tour 1
2   Tour 2
3   Tour 3

Table Tour Duration
Tour 1  3 days
Tour 2  6 days

表格旅行持续时间详情

Day          flight                           Hotel
Day 1      Amsterdam to Cairo                 Hilton
Day 2   Cairo to Aswan                        Hilton
Day 3  Cairo to Amsterdam

从2017年6月23日至2017年6月26日

Table cost Per day
Day1     500       25    
Day2   300      25
Day3  500  

Table fligh data 
Tour1   23/06/2017  26/06/2017  1350
Tour2  01/07/2017   07/07/2017 1425 (5 * 25 + 1300)

25表示希尔顿酒店每晚的住宿费用。 500表示从开罗阿姆斯特丹，阿姆斯特丹到开罗的成本航班。

300表示从开罗到阿斯旺的每次航班的费用。

如何根据航班日期设计表格关系以计算每天的费用（成本酒店+成本航班）？

Answer 1

游览时间不需要表格。首先，您可以将天数放在tour表中，但即使这样也不错，因为表Tour Duration Details中的记录已经隐含了天数。

价格随时间变化是另一回事。一个可能的模型是：

游览（tour_no，说明）
航班（flight_id，from_city，to_city）
flight_price （flight_id，from_date，to_date，price）
酒店（hotel_id，姓名）
hotel_price （hotel_id，from_date，to_date，price）
tour_days （tour_no，day_no，flight_id，hotel_id）

现在让我们说有人想在2017-08-25开始预订＃1之旅。计算成本的查询将是：

select coalesce(sum(fp.price), 0) + coalesce(sum(hp.price), 0)
from tour_days d
left join flight f on f.flight_id = d.flight_id
left join flight_price fp on fp.flight_id = f.flight_id
                          and date '2017-08-25' between fp.from_date and fp.to_date
left join hotel h on h.hotel_id = d.hotel_id
left join hotel_price hp on hp.hotel_id = h.hotel_id
                         and date '2017-08-25' between hp.from_date and hp.to_date
where d.tour_no = 1;

如何计算每天的费用（成本酒店+成本航班）取决于航班日期？
