Question

Overview of Project
This project will facilitate the Hotel owner in the Hotel to keep record of rooms and reservations and create a report on regular basis.

Project Detail
The Hotel for which you are creating this project has 5 floors and each floor has 50 rooms.
Following are types of rooms:

Standard
This category usually means the most basic room type offered by the hotel. It has basic, standard amenities and furnishings. A standard room in a Four Seasons hotel is without question much more deluxe than a standard in, say, a Holiday Inn, but there may be higher categories from which to choose. Standard rooms in hotels with higher categories often have no view or have a poor view over the dumpster or parking lot.
Price is Rs.300 / 24 Hours
This Hotel contains total of 50 rooms of this type, 10 on each floor.
Moderate
Usually a slight bit better than standard, but still not deluxe. It may refer to the room view as well as the size and type of furnishings offered.
Price is Rs. 500 / 24 Hours
This Hotel contains total of 50 rooms of this type, 10 on each floor.
Superior
This category is always subject to interpretation. It's supposed to mean superior to a standard room in both size and furnishings, but it often refers to just the view. Some hotels have only Superior rooms; the categories then are defined by the view and location of the room.
Price is Rs. 1000 / 24 Hours
This Hotel contains total of 50 rooms of this type, 10 on each floor.
Junior Suite

A "junior" suite is typically a larger room with a separate seating area. Sometimes it's got a small divider between the part of the room that the bed is in and the seating area, but it is not two separate rooms.
Price is Rs. 2000 / 24 Hours
This Hotel contains total of 50 rooms of this type, 10 on each floor.
Suite
A Suite is usually two or more rooms clearly defined; a bedroom and a living or sitting room, with a door that closes between them. Many hotels use the word "suite" to define any room with a sofa in it so be sure to check thoroughly if what you really want are the two or more separate rooms.
Price is Rs. 5000 / 24 Hour
