Introduction to Hibernate and JPA

• Overview of Object-Relational Mapping (ORM)
• Understanding Hibernate and its features
• Introduction to Java Persistence API (JPA)

Setting up Hibernate and JPA

• Configuring Hibernate with different data sources
• Setting up JPA persistence units and entity managers

Entity Mapping and Relationships

• Mapping Java entities to database tables
• Configuring primary keys and generated values
• Defining one-to-one, one-to-many, and many-to-many relationships

Entity Lifecycle and Persistence Context

• Understanding the entity lifecycle in JPA
• Managing entity states (transient, persistent, detached)
• Working with the persistence context

Querying with JPQL and Criteria API

• Writing queries using JPQL (Java Persistence Query Language)
• Using the Criteria API for type-safe queries
• Querying entities based on conditions and relationships

Fetching Strategies and Performance Optimization

• Configuring fetch strategies (e.g., eager, lazy loading)
• Understanding the impact on performance
• Implementing caching for improved performance

Transactions and Concurrency Control

• Managing transactions in JPA
• Configuring transaction boundaries and isolation levels
• Handling optimistic and pessimistic locking

Advanced Mapping Techniques

• Mapping enums, embeddable objects, and collections
• Using inheritance mapping strategies (single table, joined, table per class)
• Mapping complex relationships (e.g., self-referencing, unidirectional)

Auditing and Versioning

• Implementing audit trails for entity changes
• Tracking and managing entity versions
• Handling concurrent updates with optimistic locking

Caching and Performance Tuning

• Configuring and utilizing second-level caching
• Optimizing database access and minimizing queries
• Analyzing and improving performance bottlenecks

Transaction Management and Connection Pooling

• Configuring transaction management providers (e.g., JTA, Spring)
• Setting up connection pooling for efficient database connections
• Managing transaction boundaries and demarcation

Bulk Operations and Batch Processing

• Performing bulk inserts, updates, and deletes
• Using batch processing techniques for improved performance
• Optimizing large data operations

Integrating Hibernate and Spring

• Integrating Hibernate with Spring framework
• Leveraging Spring’s transaction management and dependency injection
• Utilizing Spring Data JPA for simplified data access

Mapping to Stored Procedures and Native SQL

• Mapping entities to stored procedures
• Executing native SQL queries with JPA
• Handling stored procedure output parameters and result sets

Testing and Debugging with Hibernate

• Unit testing with Hibernate and JPA
• Debugging common issues and exceptions with Hibernate
• Using logging and monitoring tools for troubleshooting Hibernate errors

Performance Monitoring and Optimization

• Monitoring and profiling Hibernate performance
• Identifying performance bottlenecks and optimization opportunities in Hibernate
• Using tools for performance monitoring and analysis

Best Practices and Pitfalls to Avoid

• Applying best practices for Hibernate and JPA development
• Avoiding common pitfalls and anti-patterns
• Implementing efficient data access strategies
