如何在mysql数据库中管理酒店预订系统的库存表

Question

Hi am working on a hotel booking system. Where admin can add multiple hotels and multiple rooms for each hotel.
But right now i am stuck in inventory management. For every room there will be 3 type of inventories

1. Master inventory : here admin can add number of room available for a particular type of room (Eg: Suite room) Sunday to Saturday. Available room count will be different in each days.
   
2. Periodic inventory : Here admin can choose starting date and ending date and number of room available in between those date's.
3. Daily inventory : Here admin can choose a date and number of available rooms in that particular date.

And priority order for inventory selection will be 3 -> 2 -> 1.
ie. When user select a date in website and search for hotels. First check in daily inventory if there is a daily inventory found then and its match for the user requirement then will proceed further.
Else if there is no daily inventory then will check for periodic inventory and If periodic inventory not found then will check for master inventory .
For every room there will be a master inventory but periodic and daily inventory are optional. And in master inventory you can give available rooms from Sunday to Saturday ie. for 7 days in a week. Same for periodic inventory.

Right now i am trying to implement it like this

Room table

ID integer
HOTEL_ID integer
ROOM_NAME varchar
INV_SUN integer
INV_MON integer
INV_TUE integer
.
.
INV_SAT integer
PERIODIC_STAR_DATE Date
PERIODIC_END_DATE Date
PERIODIC_SUN integer
PERIODIC_MON integer
.
.
PERIODIC_SAT integer

I don't know the method i following is correct and i have no idea how to mange daily inventory. As of now it is really difficult to search availability for hotels.
Please advice me how to redesign the database in a better way.

Answer 1

Here is your answer:
This design states that:

1. There are many hotels
2. Each hotel have many room types eg suite, 2 beds, 3 beds etc.
3. Each room type contains the rooms that have isBooked integer ie 0 or 1
4. Finally there is Booking table that stores specific hotel different rooms data

Now you can make queries eg

1. Which type of rooms in which hotels are reserved
2. How many rooms are booked
3. What rooms are booked for specific hotel from this date to this date
4. How many rooms are empty
5. Which type of rooms for which hotel are empty or reserved

so on and so forth. You can make numerous queries but this 4 tables are enough to meet your requirements in all respect

Update:

5. Admins table have different admin roles. Each admin will manage a hotel, its room_type, rooms and booking Update-2
