JDBC vs Hibernate vs JPA vs Spring Data JPA : Java Spring Boot Interview Q15

Java Spring Boot Interview Q15 !!

Which Java ORM is best for you: JDBC, Hibernate, JPA, Spring Data JPA?
In this video, we explore the key differences between JDBC, Hibernate, JPA, and Spring Data JPA — the most popular ORM and data access tools in the Java ecosystem. Whether you're preparing for interviews or working on a Java JDBC project, this is a must-watch!

We compare these technologies side by side and help you understand when to use JDBCTemplate, Hibernate, JPA or JpaRepository depending on your project needs.

✨ You'll learn:
1) How to perform entity mapping using annotations like @Entity, @Table, @Id, and @Column.
2) How Java classes map to DB tables using the Java Persistence API (JPA).
3) The role of EntityManager, SessionFactory, JPA Repository, and JDBC Template.
4) Named Query in JPA
5) JPA annotations and JPA specification
6) ORM tools and how Object-Relational Mapping works in core Java
7) Hibernate as an implementation of JPA
8) Drawbacks of JDBC

This is a complete JDBC tutorial and a Hibernate tutorial wrapped into one. We touch on JPA queries, JDBC insert/update, and practical examples, so you can build a working Java JDBC MySQL or JPA Hibernate project from scratch.

Whether you're a beginner looking for a JDBC tutorial for beginners, someone searching for Hibernate in Java, or exploring how to create tables using annotations in Spring Boot — this tutorial has it all.
