Project summary: Retail Inventory Backend Final Project with Java, Spring Boot, and Hibernate, backed by MySQL for structured data and a NoSQL database (MongoDB) for unstructured data such as product reviews.

Written by Brian McCarthy

Note on Environment: This project includes a complete Java Spring Boot 3.x source codebase located in the /backend directory. Due to platform constraints, the interactive preview in AI Studio uses a Node.js compatibility layer (server.js) that simulates the Spring Boot API behavior using Firestore. FOR FINAL SUBMISSION: Use the code in /backend.

The admin is responsible for performing the following tasks:

• Creating and maintaining store records: Provision and manage regional distribution hubs (Entity: Store).
• Managing the entire product catalog: Centralized master registry for all SKUs (Entity: Product).
• Monitoring and updating inventory across all stores: Real-time visibility and buffer adjustments (Entity: Inventory).
• Placing customer orders via the internal system: Transactional entry point (Entity: Order, Customer).
• Running backend SQL procedures: Executing complex analytical queries for business intelligence.

This project delivers:

• Models, controllers, services, and repositories: Full domain coverage for Store, Product, Inventory, Order, Customers, and Reviews.
• RESTful endpoints: Robust v1 API built in Spring Boot 3.2.
• Persistence & Hibernate: JPA-mapped entities with Hibernate validations for MySQL; Document mapping for MongoDB.
• Analytical Procedures: Implementation of native SQL queries and join-simulations for data analysis.
• Structured Logging & Exception Handling: Using SLF4J/Logback and a @RestControllerAdvice for global error mapping.

Use the files in the /backend folder. To run it locally:

1. IDE: Open /backend in IntelliJ IDEA or Eclipse.
2. Runtime: Ensure you have Java 17+ and Maven installed.
3. Configuration: Configure your application.properties with your MySQL and MongoDB credentials.
4. Execution: Run the following command in the terminal:

   mvn spring-boot:run
