Reference book

Step 1

Bands reference

Band Name (text)
Formation Date (date)
Number of Members (integer)
Most Popular Album (reference to the Albums Reference)

Albums Reference:

Album Title (text)
Release Date (date)
Number of Tracks (integer)
Sales (fixed-point number)

Step 2

MySQL

music schema

CREATE TABLE album (
album_id INT PRIMARY KEY AUTO_INCREMENT,
title VARCHAR(50) NOT NULL,
release_date DATE NOT NULL,
number_of_tracks INT NOT NULL,
sales DECIMAL(8, 3) NOT NULL);

CREATE TABLE band (
band_id INT PRIMARY KEY AUTO_INCREMENT,
name VARCHAR(50) NOT NULL,
formation_date DATE NOT NULL,
number_of_members INT NOT NULL,
most_popular_album INT UNIQUE,
FOREIGN KEY (most_popular_album) REFERENCES album(album_id));

Filling with data

INSERT INTO album (title, release_date, number_of_tracks, sales)
VALUES ("Black holes and revelations", STR_TO_DATE('19-06-2006', '%d-%m-%Y'), 12, 4500.000),
("Hybrid theory", STR_TO_DATE('24-10-2000', '%d-%m-%Y'), 12, 27000.000),
("Audioslave", STR_TO_DATE('17-11-2002', '%d-%m-%Y'), 14, 7000.000);

INSERT INTO band (name, formation_date, number_of_members, most_popular_album)
VALUES ("Muse", STR_TO_DATE('01-01-1994', '%d-%m-%Y'), 3, 1),
("Audioslave", STR_TO_DATE('01-01-2001', '%d-%m-%Y'), 4, 3),
("Linkin Park", STR_TO_DATE('01-01-1996', '%d-%m-%Y'), 9, 2);

Step 3

Tech stack: Java, Spring Boot, Spring Data JPA, HTML+JS, JQuery, MySQL

Additionally, I created a Docker container, and it worked properly, but I decided to demonstrate the whole application personally, as this is way easier than explaining how to run the Docker container :)
