# 🐾 Veterinary Clinic Management System (VetMan)

A simple Spring Boot application designed to manage the core operations of a veterinary clinic, focusing on patient records (Animals) and key operations (Vaccinations, Doctors).

✨ Features

This project provides core CRUD (Create, Read, Update, Delete) functionalities for the following entities:

• Animals (Patients): Comprehensive record-keeping for every animal, including species, breed, color, and unique identification.
• Customers: Owner information for each animal.
• Doctors: Management of veterinary staff information.
• Vaccines: Registration of different vaccine types and their codes.
• Vaccinations: Records of applied vaccines, adhering to specific business rules.

🚀 Key Business Logic Implemented

The system enforces important business rules to ensure data integrity:

1. Unique Records

• Doctor/Customer: Email and phone numbers must be unique across all records.
• Vaccine: Each vaccine type must have a unique code.

2. Vaccination Rules (The "Same Vaccine Block")

• A new vaccination record for an animal cannot be created if an active vaccination of the same type (same vaccine code) already exists and its protection end date has not passed.
  • Example: If a Rabies shot is active until 2026-11-01, a new Rabies shot cannot be applied until after that date.

💻 Technology Stack

• Backend: Java 21+
• Framework: Spring Boot 3
• Database: PostgreSQL (Recommended for production) or H2 (for development/testing)
• Persistence: Spring Data JPA & Hibernate
• API Testing: Postman
• Build Tool: Maven

🛠️ Setup and Installation

1. Clone the Repository:

   git clone [YOUR_REPO_URL]
   cd vet-management-system

2. Database Configuration:

   • Update src/main/resources/application.properties with your database settings (PostgreSQL recommended).

   spring.datasource.url=jdbc:postgresql://localhost:5432/vet_db
   spring.datasource.username=postgres
   spring.datasource.password=yourpassword
   spring.jpa.hibernate.ddl-auto=update

3. Run the Application: You can run the application directly from your IDE (IntelliJ/VS Code) or use Maven:

   ./mvnw spring-boot:run
