How can complex JSON structures be broken down and stored in multiple tables in a relational database for efficient retrieval?

Complex JSON structures can be broken down and stored in multiple tables in a relational database by first identifying the different entities and relationships within the JSON data. Each entity can then be represented as a separate table in the database, with foreign keys used to establish relationships between them. This allows for efficient retrieval of the data through SQL queries that join the relevant tables based on the established relationships. 

// Assuming you have a JSON object $json_data containing complex data structure

// Parse JSON data
$data = json_decode($json_data, true);

// Store data in separate tables
// Example: Users table
$users = $data['users'];
foreach ($users as $user) {
    // Insert user data into Users table
}

// Example: Posts table
$posts = $data['posts'];
foreach ($posts as $post) {
    // Insert post data into Posts table
    // Use foreign keys to establish relationships with Users table
}

// Example: Comments table
$comments = $data['comments'];
foreach ($comments as $comment) {
    // Insert comment data into Comments table
    // Use foreign keys to establish relationships with Users and Posts tables
}
