Real-World Analogy
Think of Spring Framework as a powerful car engine (V8 engine). Think of Spring Boot as the complete ready-to-drive luxury sports car built around that engine, complete with power steering, GPS, air conditioning, and a push-to-start ignition button!
Core Relationship Explained Simply
Spring Boot is not a replacement for Spring. Instead, Spring Boot is built ON TOP of the Spring Framework. It gives you all the core power of Spring without the setup pain.
