Hibernate

Object-Relational Mapping (ORM) framework for Java for storing/updating data into Database
Without Hibernate, you have to write long, tedious, and error-prone SQL queries manually inside your Java code using standard JDBC.

Example Storing data into Users Table
With Hibernate

import javax.persistence.*;

@Entity                     // Tells Hibernate this class maps to a DB table
@Table(name = "users")      // Name of the DB table
public class User {

    @Id                     // Primary key
    @GeneratedValue        // Auto-increment the ID
    private Long id;

    private String name;
    private String email;

    // Constructors, Getters, and Setters...
    public User(String name, String email) {
        this.name = name;
        this.email = email;
    }
}
Without Hibernate(Raw JDBC)

String sql = "INSERT INTO users (name, email) VALUES (?, ?)";   //manually construct SQL strings
PreparedStatement stmt = connection.prepareStatement(sql);
stmt.setString(1, "Alice");
stmt.setString(2, "alice@example.com");
stmt.executeUpdate(); // Lots of boilerplate code!
