Description
In this course you will learn about JPA, ORM different concepts about them. Then you will learn about how to use different concepts in real world project. Later you will learn about Entity, Entity Manager, Query, Criteria, Persistence Context, Persistence Unit, Transaction, Lazy loading, Relationships, SpringData JPA. Finally you will learn to use JPA without Springboot and JPA with Springboot by doing two real world projects.
Following is the list of topics that you will learn in this course:
Introduction to JPA
Overview of Java Persistence API (JPA) Evolution from JPA 1 to JPA 2 Key features and benefits

Entity Basics

Creating JPA entities Entity lifecycle and states Annotations (@Entity, @Id, @GeneratedValue, etc.) Embeddable and embedded objects

Mapping Entities

Mapping entity attributes One-to-One, One-to-Many, and Many-to-One relationships Many-to-Many relationships Mapping inheritance hierarchies (Single Table, Joined, and Table per Class strategies)

JPQL (Java Persistence Query Language)

Overview of JPQL Querying entities with JPQL Named queries JPQL functions and aggregation

Criteria API

Introduction to Criteria API Building type-safe queries Predicate, CriteriaQuery, and CriteriaBuilder

Transactions and Persistence Context

Managing transactions in JPA Entity Manager and Persistence Context Transaction demarcation (declarative and programmatic)

Advanced Mapping Techniques

Embedded objects and collections Lazy and eager loading strategies Optimistic and pessimistic locking Custom converters and mappings

Performance Tuning and Best Practices

Fetch strategies and batching Caching strategies (1st and 2nd level cache) Query optimization Best practices for efficient data access

Integration with Java EE and Spring

Using JPA in Java EE applications Spring Data JPA integration Transaction management with JTA and Spring

Testing and Debugging JPA Applications

Unit testing JPA entities and queries Debugging common JPA issues Integration testing with embedded databases

Migration and Upgrading

Migrating from JPA 1 to JPA 2 Upgrading JPA providers Handling version-specific issues

Future of JPA

Trends and advancements in ORM frameworks JPA vs. other ORM solutions Considerations for modern application development.
After this course you will become pro level developer who will be very confident to work in any project which uses JPA or SpringData JPA.
