ProblèmeComment calculer le coût par jour (coût hôtel + coût vol) selon la date du vol?

Comment calculer le coût par chaque jour (hôtel + vol des coûts des coûts) en fonction de la date de vol?

J'ai besoin de faire des relations de conception de base de données pour calculer le coût par tour pour les touristes en Egypte. coût de vol + coût de l'hôtel (prix de la chambre + services) par chaque jour pour personne en fonction de la date de vol

Supposons que je vol à la date 23/06/2017 d'Amsterdam en Egypte

et du Caire à Amsterdam 26/06/2017 va revenir

Pour que le calcul sera comme suit:

Table tour 
1 Tour 1 
2 Tour 2 
3 Tour 3 

Table Tour Duration 
Tour 1 3 days 
Tour 2 6 days

Tableau Durée de la visite Détails

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

De 23/06/2017 à 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 représentent un hébergement économique par nuit à l'hôtel hilton. 500 représentent le vol de coût du Caire Amsterdam, Amsterdam au Caire. 300 représentent le coût par vol du Caire à Assouan.

Comment concevoir des relations de table pour calculer le coût par jour (coût hôtel + coût de vol) en fonction de la date du vol?

Les données que vous affichez pour Détails de la durée de la tournée de table et coût de la table Par jour sont uniquement pour la tournée # 1, n'est-ce pas? –

Les prix des vols et les prix des hôtels changent au fil du temps. Cette tournée n'est-elle donc valable que pendant un certain temps et une fois l'un des prix modifié, vous invalidez la tournée n ° 1 et créez une nouvelle tournée similaire? Ou comment envisagez-vous d'y aller? –

oui pour tour 1 seulement –

Vous n'avez pas besoin d'une table pour la durée de la visite . Tout d'abord, vous pourriez avoir mis le nombre de jours juste dans la table tour, mais même ce serait une mauvaise idée, car le nombre de jours est déjà implicitement donné par les enregistrements dans la table Tour Duration Details.

Les prix changeant au fil du temps sont une autre chose à considérer.Un modèle possible est la suivante:

Tour (tour_no, description)
vol (flight_id, from_city, to_city)
flight_price (flight_id, from_date, to_date, prix)
hôtel (nom de l'hôtel, nom)
hotel_price (hotel_id, from_date, to_date, prix)
tour_days (tour_no, day_no, flight_id, hotel_id)

Maintenant, disons que quelqu'un veut réserver tour # 1 à partir 25/08/2017. La requête pour calculer le coût serait:

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;

merci pour la réponse calcul basé sur le détail durée tableau –

pouvez-vous s'il vous plaît voir l'image dans le message original –
