Implementing Caching Strategies

Create an example of implementing caching strategies to improve the performance of SQL queries in a system using RAG components.
<!-- HTML structure to display query results -->
<div id='query-results'></div>
This HTML snippet provides a container where query results will be displayed after fetching from the cache or database.
/* CSS styling for the query results container */
#query-results {
    padding: 10px;
    border: 1px solid #ccc;
    margin-top: 20px;
This CSS snippet styles the query results container.
// JavaScript to implement caching strategies
const cache = {};

function executeQuery(sql) {
    // Check if the result exists in the cache
    if (cache[sql]) {

    // If not in cache, execute the SQL query
    database.query(sql).then(results => {
        // Store the results in the cache
        cache[sql] = results;
        // Display the results

function displayResults(results) {
    // Display the results in the query-results element
    const resultsContainer = document.getElementById('query-results');
    resultsContainer.innerHTML = JSON.stringify(results, null, 2);

// Example SQL query
const sqlQuery = 'SELECT * FROM users';
// Execute the query on page load
window.onload = () => executeQuery(sqlQuery);
This JavaScript snippet includes caching logic and functions to execute and display results of SQL queries. It uses a simple in-memory cache object to store query results.
