Placement Management System (Spring Boot)

Overview

The Placement Management System is designed to manage student placements within an organization. It allows administrators to track student profiles, job openings, and placement activities.

Features

• Student registration and profile management
• Job posting and application tracking
• Interview scheduling and feedback
• Placement statistics and reporting

Technologies Used

• Java Spring Boot: Backend framework
• Hibernate (JPA): Object-relational mapping
• MySQL: Database
• Thymeleaf: Frontend templating
• Bootstrap: Styling

Design Principles

SOLID Principles

1. Single Responsibility Principle (SRP): Each class should have one reason to change. Avoid mixing responsibilities in a single class.

   • Example: Separate report generation and email sending logic into different classes.

2. Open/Closed Principle (OCP): Software entities (classes, modules, functions) should be open for extension but closed for modification.

   • Design classes to allow adding new features without altering existing code.

3. Liskov's Substitution Principle (LSP): Objects of a superclass should be replaceable with objects of a subclass without affecting correctness.

   • Ensure that subclasses adhere to the contract defined by their superclass.

4. Interface Segregation Principle (ISP): Clients should not be forced to depend on interfaces they do not use.

   • Split large interfaces into smaller, more focused ones.

5. Dependency Inversion Principle (DIP): High-level modules should not depend on low-level modules; both should depend on abstractions.

   • Use dependency injection to invert control and decouple components.

GRASP Principles

1. Information Expert: Assign responsibilities to the class with the most information required to fulfill them.
2. Creator: Assign the responsibility of creating an object to the class that has the necessary information.
3. Controller: Assign the responsibility of handling system events to a controller class.
4. Low Coupling: Minimize dependencies between classes.
5. High Cohesion: Group related responsibilities together within a class.

Design Patterns

Explore the following design patterns for your Placement Management System:

1. Factory Method: Create instances of different placement-related objects (e.g., student, job, interview) based on specific criteria.
2. Observer: Notify interested parties (e.g., students, administrators) about placement events (e.g., job postings, interview schedules).
3. Strategy: Define different algorithms for ranking students based on placement criteria (e.g., GPA, skills).
4. Decorator: Enhance student profiles dynamically by adding additional information (e.g., certifications, projects).
