# MySQL Database Optimization and Identifying Slow Queries

## Why Databases Experience Degradation Over Time

Frequent record updates and deletions cause disk fragmentation within table data spaces. Bloated revision logs and transient rows compound query response latencies.

## Optimizing Tables via phpMyAdmin

1. Log into cPanel and open **phpMyAdmin**.
2. Select your database, scroll down, and click **Check all**.
3. From the action dropdown, select **Optimize table**.
4. This defragments index trees and reclaims unallocated storage space.

## InnoDB vs MyISAM Engine Comparison

Always migrate legacy MyISAM tables to **InnoDB** to gain row-level locking concurrency and ACID-compliant transactional reliability.
