HOTEL DATABASE MANAGEMENT SYSTEM Part A: Describe the situation. Your description should be brief and relatively informal (maximum length 1 A4 page) Scenario: "The owner of a Hilton hotel would like to have a hotel management system built for the hotel.

The hotel is located in major cities and tourist attraction areas of Darwin, Australia. The owner hired an expert in database concept to design the database for his hotel. The Hotel is identified by the Hotel Code, Hotel Name, Hotel Number, Location, Employee ID and Guest ID. In the hotel, employees are hired to perform various duties. So, there are number of employees in the hotel.

So, the attributes of the employee's include Employee ID, Name, Date of Birth, Phone and Room category. Employees are tasked to manage rooms based on the Room category attribute assigned by the hotel to the employees. In the hotel, guests make reservations for rooms of their choice. The reservations of the guest are also recorded in the directory which can be identified as Reservation No, Guest ID, Hotel Code, Room Type and Room ID. The attributes of the Guest are Guest ID, Reservation No, Name, Phone, Address and Room ID.

According to the guest choice, they are placed in the different categories of rooms based on Room ID, Room Type, Guest ID, Reservation No and Room category. So, guest are billed according to the type of room they have reserved which can be identified by Invoice No, Guest ID, Room Charge and Miscellaneous Charges. Business Rules/Assumption 1. One guest makes one reservation. 2.

Hotel have many reservations. 3. Hotel can have many guests. 4. Many guests can occupy one room.

5. One room can have more than one guest. 6. One employee manages one room. 7.

One room can hold one reservation. 8. Many Employees work in hotel. 9. Guests can make reservation in hotel through which rooms are occupied by guests.

10. Many employees work in hotel who are then assigned by hotel to manage one room. 11. Guests have many links. 12.

Guests pay bill for the room they are occupying.

Hotel Database Management System

Part A: Description of the Situation

The current scenario revolves around the formation of a comprehensive hotel management system for a Hilton hotel situated in the bustling tourist enclave of Darwin, Australia. The hotel owner aims to optimize operations through an efficient database management system that captures vital data elements concerning hotel operations, guest management, and employee allocation.
At the core of this database solution, the system identifies several critical entities including the hotel, employees, rooms, guests, and reservations, each characterized by distinct attributes. The hotel is uniquely identified via a Hotel Code, supplemented by essential details such as Hotel Name, Location, and Hotel Number. For operational efficiency, the hotel employs numerous staff members, each defined by attributes like Employee ID, Name, Date of Birth (DOB), Phone, and Room Category.
Reservations form a critical component of the hotel management framework as they capture data pertaining to guest bookings. Each reservation is tagged with a unique Reservation Number and associated with attributes such as Guest ID, Hotel Code, and Room Type. Guests themselves are indexed by Guest ID, with additional information captured, including Name, Phone, Address, and Room ID, thereby facilitating better management and billing processes.
Room management is paramount, as various room types cater to diverse guest preferences. Each room is thus characterized by attributes such as Room ID, Room Type, along with corresponding billing information, noting charges associated with their stay encapsulated in the Invoice records. The business rules laid out streamline operations, ensuring clarity in reservation systems, guest accommodation, and billing processes.
This proposed database serves as a robust, scalable solution that accommodates the operational complexities of hotel management, enhances customer experiences, and promotes efficient resource utilization.

Part B: Mapping the ER Diagram to 3NF & Normalization

Entity-Relationship Diagram (ER Diagram)
1. Hotel
- Attributes: Hotel Code, Employee ID, Hotel Name, Location, Hotel Number.
2. Employee
- Attributes: Employee ID, Name, Date of Birth (DOB), Phone, Room Category.
3. Room
- Attributes: Room ID, Room Type, Guest ID, Reservation Number.
4. Reservation
- Attributes: Reservation Number, Guest ID, Hotel Code, Room Type, Room ID.
5. Guest
- Attributes: Guest ID, Reservation Number, Name, Phone, Address.
6. Bill
- Attributes: Invoice Number, Guest ID, Room Charge, Miscellaneous Charges.
Translation to Normalized Tables (3NF)
Normalization aims to eliminate redundancy and ensure data integrity. The following tables represent the 3NF version of the hotel database:
1. Hotel
- Attributes: Hotel Code (PK), Hotel Name, Location, Hotel Number.
2. Employee
- Attributes: Employee ID (PK), Name, DOB, Phone, Room Category.
3. Room
- Attributes: Room ID (PK), Room Type, Employee ID (FK), Hotel Code (FK).
4. Reservation
- Attributes: Reservation Number (PK), Guest ID (FK), Hotel Code (FK), Room ID (FK).
5. Guest
- Attributes: Guest ID (PK), Reservation Number (FK), Name, Phone, Address.
6. Bill
- Attributes: Invoice Number (PK), Guest ID (FK), Room Charge, Miscellaneous Charges.
Functional Dependencies Analysis
To achieve 3NF, we need to identify the functional dependencies:
- Hotel:
- Hotel Code → (Hotel Name, Location, Hotel Number)
- Employee:
- Employee ID → (Name, DOB, Phone, Room Category)
- Room:
- Room ID → (Room Type, Hotel Code)
- Reservation:
- Reservation Number → (Guest ID, Hotel Code, Room ID)
- Guest:
- Guest ID → (Reservation Number, Name, Phone, Address)
- Bill:
- Invoice Number → (Guest ID, Room Charge, Miscellaneous Charges)
Ensuring 3NF
1. The tables must be in Second Normal Form (2NF) without partial dependencies, which we've ensured by isolating the primary keys and attributes against their respective relationships.
2. To achieve transitive dependency resolution, all non-prime attributes (attributes that are not part of any candidate key) are moved to separate tables, ensuring that each table contains distinct data categories.
This approach guarantees minimized redundancy and improved data integrity, establishing a structured database capable of effectively managing hotel operations while ensuring easy access to relevant information for employees.

Conclusion

In summary, this hotel management database outlines a structured framework that accounts for relationships and manages data effectively regarding hotel operations, staff assignments, and guest management. By adhering to normalization principles, the database not only facilitates optimal data retrieval but also enhances overall operational efficiency, addressing the dynamic requirements of the hospitality industry.
