Hibernate Project with Many-to-Many Mapping

This Hibernate project implements a many-to-many mapping between the Course and Student entities using a join table. In this mapping, a course can have multiple students enrolled, and a student can be enrolled in multiple courses. The join table holds foreign keys from both tables to establish the relationship. No cascading delete operations are applied, ensuring that deleting a course does not delete its associated students, and deleting a student does not delete their enrolled courses. Lazy loading is utilized to load data only when requested, optimizing performance.

Features

• Many-to-Many Mapping: Implements a many-to-many mapping between Course and Student entities, allowing courses to have multiple students and students to be enrolled in multiple courses.
• Join Table: Utilizes a join table to establish the relationship between courses and students, holding foreign keys from both tables.
• Lazy Loading: Implements lazy loading to load data only when requested, optimizing performance by reducing unnecessary data retrieval.
• Efficient Data Management: Enables efficient management of course enrollment and student registration without cascading delete operations.

Project Structure

The project structure includes the following components:

• Course entity: Represents a course with details such as title, description, and enrolled students.
• Student entity: Represents a student with details such as name, email, and enrolled courses.
• Join table: Stores the relationship between courses and students by holding foreign keys from both tables.
• Main class: Contains the main method to demonstrate CRUD operations and many-to-many mappings.

Usage

To run the Hibernate project with many-to-many mappings locally, follow these steps:

1. Clone this repository.
2. Open the project in your preferred IDE.
3. Update the Hibernate configuration file (hibernate.cfg.xml) with your database connection details.
4. Run the Main class to execute the CRUD operations and observe the behavior of many-to-many mappings with lazy loading.
