What are the best practices for storing dynamic data like troop production and moving armies in a MySQL database for a browser game?

Storing dynamic data like troop production and moving armies in a MySQL database for a browser game requires proper database design and efficient querying to handle real-time updates and retrievals. One approach is to have tables for troops, armies, and movements, with appropriate indexes and relationships to ensure data integrity and performance.

// Sample code for creating tables for troop production, armies, and movements in MySQL database

// Create table for troops
CREATE TABLE troops (
    id INT PRIMARY KEY,
    name VARCHAR(50),
    attack INT,
    defense INT
);

// Create table for armies
CREATE TABLE armies (
    id INT PRIMARY KEY,
    player_id INT,
    troop_id INT,
    quantity INT,
    location VARCHAR(50)
);

// Create table for movements
CREATE TABLE movements (
    id INT PRIMARY KEY,
    army_id INT,
    from_location VARCHAR(50),
    to_location VARCHAR(50),
    start_time DATETIME,
    end_time DATETIME
);
