飛行機の日付に応じて、毎日の費用を計算する方法（ホテルと料金のフライト）

-1

飛行日付に応じて、毎日（コストホテル+コスト飛行）あたりのコストを計算するためにどのように問題飛行機の日付に応じて、毎日の費用を計算する方法（ホテルと料金のフライト）

？

私は、エジプトの観光客のためのツアー1回あたりの費用を計算するためにデータベースの設計関係を作る必要があります。飛行日付に基づいて、人のために毎日あたりフライトコスト+ホテルコスト（部屋代+サービス）

私はエジプト

し、カイロからアムステルダムへアムステルダムから日付23/06/2017に飛行を持っていると仮定

Table tour 
1 Tour 1 
2 Tour 2 
3 Tour 3 

Table Tour Duration 
Tour 1 3 days 
Tour 2 6 days

表ツアー所要時間の詳細

012：26/06/2017だからその計算は以下のようになりますバック

戻ります23/06/2017から26/06/2017

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から

は、ヒルトン・ホテルで一泊コストのご宿泊を表します。 500は、カイロアムステルダム、アムステルダムからカイロへの航空便を表しています。

300は、カイロからアスワンへの飛行1回あたりの費用を表します。

飛行機の日付に応じて、毎日のコストを計算するためのテーブルリレーションを設計するにはどうすればよいですか？

テーブルツアー期間の詳細と1日あたりのテーブル費用に表示されているデータは、ツアー＃1の場合のみ、正しいのでしょうか？ –

フライト料金とホテル価格は時間とともに変化します。このツアーは特定の期間のみ有効ですが、料金の変更が行われると、ツアー＃1が無効になり、同様の新しいツアーが作成されます。またはこれについてどうやって計画していますか？ –

ツアー1のみ –

に基づいて計算するショーです見ることができます。まず、tourテーブルの日数だけを置くことができましたが、テーブルTour Duration Detailsのレコードによって暗黙的に日数が与えられているので、これは悪い考えです。

時間の経過とともに価格が変化することも考慮する必要があります。

ツアー（tour_no、説明）
飛行（flight_id、from_city、to_city）
flight_price（flight_id、FROM_DATE、TO_DATE、価格）
ホテル（ホテル名、ホテル名）
hotel_price（hotel_id、FROM_DATE、TO_DATE、価格）
tour_days（tour_no、day_no、flight_id、hotel_id）

今度は、誰かが2017年8月25日に開始するツアー＃1を予約したいとしましょう。

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;
