How can the concept of normalization be applied effectively when structuring the database for a PHP project involving tables and calendars?

When structuring the database for a PHP project involving tables and calendars, the concept of normalization can be applied effectively by breaking down the data into separate tables to reduce redundancy and improve data integrity. This can be achieved by creating separate tables for entities like events, dates, and attendees, and establishing relationships between them using foreign keys.

CREATE TABLE events (
    event_id INT PRIMARY KEY,
    event_name VARCHAR(50),
    description TEXT
);

CREATE TABLE dates (
    date_id INT PRIMARY KEY,
    event_id INT,
    event_date DATE,
    FOREIGN KEY (event_id) REFERENCES events(event_id)
);

CREATE TABLE attendees (
    attendee_id INT PRIMARY KEY,
    event_id INT,
    attendee_name VARCHAR(50),
    FOREIGN KEY (event_id) REFERENCES events(event_id)
);
