Create a database for the High Hopes Bed & Breakfast owned by Pauline Jones, including entities such as Bedrooms, Guests, Bookings, and Outdoor activities. The database should include appropriate attributes, primary keys, foreign keys, and relationships. You need to produce a diagram in MS Word illustrating the entities, attributes, relationships, and key constraints. Then, implement this database in MS Access by creating tables corresponding to each entity, choosing suitable data types, and establishing relationships between tables. Additionally, create user-friendly forms for data entry, without adding sample data. Develop queries to determine: the number of guests from Canada, guests who reserved more than one room, and guests who booked skiing as an outdoor activity, sorted in descending order by customer name.

The task of designing and implementing a relational database for High Hopes Bed & Breakfast involves several critical steps that ensure data integrity, ease of access, and operational efficiency. Initially, the conceptual design requires identifying core entities—such as Bedrooms, Guests, Bookings, and Outdoor Activities—and defining their attributes, primary keys, and the relationships among them. This foundational step is best visualized through an Entity-Relationship (E-R) diagram created in MS Word, which maps out these components and their interactions.
The Bedrooms entity would include attributes like BedroomID, Name, View (Mountain or Lake), and perhaps Availability status. Guests would have attributes such as GuestID, Name, Country, Contact details, and special requirements. Bookings would link Guests and Bedrooms, capturing details like BookingID, GuestID (foreign key), BedroomID (foreign key), Check-in date, Check-out date, and whether an outdoor activity was booked. Outdoor Activities would have ActivityID, Name (e.g., skiing, cycling), Cost, and possibly a description.
Following the conceptual design, the next step involves translating the ER diagram into a physical database in MS Access. Tables are created for each entity, with data types chosen for each attribute—such as Text, Date/Time, Currency, and Number. Appropriate input masks and validation rules are incorporated to maintain data quality—for example, validating date formats or ensuring numerical fields only contain valid values. Establishing relationships between tables involves setting primary keys and foreign keys; for instance, the Bookings table would have foreign keys linking to the Guests, Bedrooms, and Outdoor Activities tables, enforcing referential integrity.
User interface is enhanced through the development of forms that simplify data entry and retrieval. Forms for booking entries, guest management, and outdoor activity selections allow staff or users to input data efficiently without directly manipulating tables, reducing errors and maintaining consistency. Creating queries further enhances the database's utility. For example, a query to find the number of guests from Canada involves filtering the Guests table by the Country attribute. To identify guests with multiple room bookings, the query would group bookings by GuestID and count the number of rooms booked per guest. Similarly, a query listing guests who booked skiing sorts these results in descending order of guest names, providing actionable insights.
This systematic approach to database design not only optimizes operational workflows but also ensures scalability and data integrity. It exemplifies best practices in database development by emphasizing conceptual modeling, proper table design, enforced relationships, and user-centric data interfaces. Effective database implementation supports the effective management of guest information, booking details, and activity bookings, thus enhancing the overall guest experience and operational efficiency at High Hopes Bed & Breakfast.
