• Index frequently queried columns.
• Remove unused indexes.
• Regularly analyze and maintain indexes.

SELECT name, salary
FROM employees
WHERE department = 'Engineering' AND salary > 70000
ORDER BY salary DESC;

// Initialize the current index
let currentIndex = 0;

// Array of image file names
const images = ['image1.jpg', 'image2.jpg', 'image3.jpg'];

// Function to display the current image
function showImage(index) {
    console.log('Displaying Image:', images[index]);
}

// Function to display the next image
function nextImage() {
    currentIndex = (currentIndex + 1) % images.length;
    showImage(currentIndex);
}

// Function to display the previous image
function prevImage() {
    currentIndex = (currentIndex - 1 + images.length) % images.length;
    showImage(currentIndex);
}

// Show the initial image
showImage(currentIndex);
