Master Hibernate and Java Persistence with ENCODE-IT

Course Overview:

Hibernate is the most widely used Object-Relational Mapping (ORM) framework in Java, allowing developers to map Java objects to database tables, simplifying database interaction, and enabling smoother integration between the application and relational databases. ENCODE-IT’s Hibernate Training is designed to give you in-depth knowledge of Hibernate, JPA (Java Persistence API), and how to leverage these tools for building efficient, high-performance Java applications.

In this course, you’ll explore key topics like Hibernate configuration, CRUD operations, querying data with HQL (Hibernate Query Language), mapping Java objects to relational databases, session management, and transaction handling. You will also learn about advanced Hibernate features, including lazy loading, caching, and optimizing performance.

Upon completion of this course, you will have the skills required to build robust data-driven applications, optimize data access layers, and use Hibernate and JPA in real-world scenarios for enterprise-level solutions.

Salary Scale in India:

Hibernate developers are in high demand in the software industry, particularly in companies building data-intensive applications. The average salary for a Hibernate developer in India ranges between ₹6-12 LPA for entry-level positions, and can increase to ₹15-25 LPA for more experienced developers, especially those working with JPA, Spring Data, and Microservices architectures.
