What is the main purpose of using JPA in Java application development?

The main goal of using JPA (Java Persistence API) is to simplify working with databases in Java applications through object-relational mapping (ORM). JPA allows developers to work with data as Java objects rather than writing SQL queries directly.

Advantages:

• Automatic conversion of objects to database records and vice versa
• Management of object lifecycle and transactions
• Caching and query optimization

Example of using JPA:

@Entity
public class User {
    @Id
    private Long id;
    private String name;
    // getters and setters
}

// In code, you can work with User objects, and JPA will handle saving to the database
