Milestone 3: Data Persistence (Spring Data JPA)

🟨 Milestone 3: Data Persistence (Spring Data JPA)

Welcome to the data layer. Here, we learn how to make our data “Persistent”—meaning it stays safe in a database even when the power goes out.

📚 Slow-Paced Deep Dives

• Module 1: Entities & JPA (The Warehouse Map): Mapping Java classes to SQL tables.
• Module 2: Repositories (The Automatic Clerk): Building query interfaces with zero SQL.
• Module 3: Entity Relationships (The Connected Shelves): Linking data together with One-to-Many and Many-to-One.

🥅 Milestone Goals

1. Map a C# class to a real SQL database table.
2. Perform CRUD (Create, Read, Update, Delete) operations using Repositories.
3. Design a Relational Schema between two different Entities.
4. Understand Lazy Loading to keep your app fast.
