Java Persistence: High-Performance JPA and Hibernate

Is your Java application slowed down by inefficient database queries? Many performance issues originate in the data access layer. This course provides a practical path to writing fast, scalable, and maintainable persistence code using JPA and Hibernate. You'll move beyond basic CRUD operations to truly understand how an Object-Relational Mapping (ORM) framework operates. By mastering the fundamentals and learning to identify common performance bottlenecks, you will gain the skills to build robust applications that interact with databases efficiently. What you'll learn: - Understand core ORM principles and the relationship between JPA and Hibernate. - Master entity mappings, lifecycle events, and essential relationship types (one-to-one, one-to-many, many-to-many). - Apply effective fetching strategies to solve N+1 query problems and prevent unnecessary data loading. - Learn to use connection pooling and batch processing to significantly improve application throughput. - Practice writing powerful and optimized queries using both the Java Persistence Query Language (JPQL) and the Criteria API. - Implement effective caching and concurrency control strategies to handle high-demand scenarios. This course starts with foundational concepts like session management and entity states before progressing to advanced topics in querying, optimization, and transaction management. Each topic is explained through clear text and practical code examples you can study and adapt. This course is for Java developers who want to learn JPA and Hibernate from the ground up or for those who wish to deepen their understanding of persistence performance. A solid grasp of Java and basic SQL is expected, but no prior ORM experience is necessary. Start building faster and more reliable data-driven Java applications today.
