Spring boot with ionic (backend)

📘 General Objective

The case study is for demonstrate, in practice, how a conceptual model (domain model at the analysis level) can be implemented using the object-oriented paradigm, applying industry standards and best practices.

I will explore a comprehensive conceptual model as a case study to showcase the practical implementation in an object-oriented programming language, covering the following topics:

---

📌 Requirements

• Spring boot 3.4.5
• Java SE 17
• Ionic
• JPA => Hibernate

📌 Topics Covered

📊 Understanding UML Diagrams

• ✅ Reading and understanding Class Diagrams
• ✅ Reading and understanding Object Diagrams

---

🔗 Associations

• 🔁 One-to-Many / Many-to-One
• 🔁 One-to-One
• 🔁 Many-to-Many (Standard)
• 🔁 Many-to-Many with Association Class
• 🔁 Bidirectional / Unidirectional Associations

---

⚙️ Object-Oriented Concepts

• 🧱 Independent / Dependent Concepts
• 🧾 Association Class
• 🧬 Inheritance
• 🔢 Enumerations
• 📦 Embedded Attributes (e.g., ItemPedidoPK)
• 📚 Element Collections (e.g., a client's phone numbers)

---

✅ Software Engineering Best Practices

Throughout the chapter, we will also discuss and demonstrate Software Engineering Best Practices, including:

• 📐 Layered Architecture Development
• 🚨 Exception Handling

---

I show how to move from abstract domain models to concrete implementations using object-oriented principles and clean code practices.
