How do you optimize database queries in PrestaShop?

Answer: To optimize database queries in PrestaShop, you can:

1. Enable Caching: Use caching systems like APCu or Memcached to reduce repeated database queries.
2. Optimize Indexes: Ensure that database tables have appropriate indexes for frequently queried columns.
3. Review SQL Queries: Use the built-in SQL query logging to identify slow queries and optimize them.
4. Upgrade to Latest Version: Keep PrestaShop and its modules updated to benefit from performance improvements.
5. Minimize Joins: Limit the use of complex joins in queries where possible.
6. Use Database Optimization Tools: Utilize tools like phpMyAdmin to clean up and optimize your database.
7. Implement Lazy Loading: Load data only when necessary to reduce initial query load.
8. Reduce Data Size: Archiving or deleting unnecessary data can help improve performance.

Combining these techniques can significantly enhance the speed and efficiency of database interactions in PrestaShop.
