        <h1>Bienvenido a SQL Cheatsheet</h1>
        <p>SQL (Structured Query Language) es un lenguaje estándar utilizado para interactuar con bases de datos
            relacionales.
            Permite crear, modificar y consultar datos de manera eficiente. Esta cheatsheet está diseñada para ayudarte
            a
            aprender y recordar las instrucciones más comunes de SQL.</p>

        <h2>Qué aprenderás aquí:</h2>
        <ul>
            <li><strong>Query Basics:</strong> SELECT, INSERT, UPDATE, DELETE y WHERE.</li>
            <li><strong>Filtrado y orden:</strong> Operadores, ORDER BY, LIKE, IN, BETWEEN, GROUP BY y HAVING.</li>
            <li><strong>Funciones:</strong> Funciones agregadas (COUNT, SUM, AVG, MAX, MIN), de cadena, numéricas y de
                fecha.</li>
            <li><strong>Tablas y Constraints:</strong> CREATE, ALTER, DROP TABLE, PRIMARY KEY, FOREIGN KEY, UNIQUE,
                CHECK, DEFAULT.</li>
            <li><strong>Índices y Auto Increment:</strong> Mejora el rendimiento de las consultas con índices y claves
                autoincrementales.</li>
