JPA - Develop Database Applications
JPA (Java Persistence API) is a specification for managing relational data in Java applications. It simplifies database interactions by mapping Java objects to database tables using ORM (Object-Relational Mapping). JPA enables developers to perform CRUD operations efficiently without writing complex SQL queries.
Key Features of JPA - Develop Database Applications
- Object-Relational Mapping (ORM) to map Java objects to database tables
- Supports CRUD operations with minimal SQL coding
- Entity lifecycle management and caching
- JPQL (Java Persistence Query Language) for database queries
- Transaction management integration
- Supports relationships like One-to-One, One-to-Many, Many-to-Many
Before learning JPA, you should have a solid understanding of core Java and object-oriented programming. Basic knowledge of relational databases and SQL is essential. Familiarity with JDBC and database concepts will help you grasp JPA more effectively.
