Grokking Spring Persistence

Understanding persistence concepts with the Spring Boot framework

Part 01 — Representing Object Associations in the Database

Understanding the different ways in which you can represent the relationships between classes in a relational database

• Introduction
• The "Association Type Predictor" Method
• Introduction
• A. The One-to-One Association
  • A1. One-to-One: Single Table
  • A2. One-to-One: Tables Sharing the Primary Key
  • A3. One-to-One: Distinct Tables
• B. The One-to-Many Association
  • B1. One-to-Many: Distinct Tables
  • B2. One-to-Many: Link Table
• C. The Many-to-Many Association
  • C1. Many-to-Many: Link Table
  • C2. Many-to-Many: Link Table with Primary Key

Part 02 — Using JPA for Modeling Entity Relationships

Annotating your classes to declare the persistence relationships in your domain model

• Introduction

• A. Mapping One-to-One Associations

  • A1. One-to-One: Mapping an Embedded One-to-One Association
    • Sample 1 — One-to-One: Embedded
  • A2. One-to-One: Tables Sharing the Primary Key
  • A3. One-to-One: Distinct Tables
    • A) Unidirectional One-to-One Association
      • Sample 2 — One-to-One: Unidirectional
    • B) Bidirectional One-to-One Association
      • Sample 3 — One-to-One: Bidirectional

• B. Mapping One-to-Many and Many-to-One Associations

  • B1. One-to-Many: Distinct Tables
    • A) Unidirectional One-to-Many Association
      • Sample 4 — One-to-Many: Unidirectional
    • B) Bidirectional One-to-Many Association
      • Sample 5 — One-to-Many: Bidirectional
  • B2. One-to-Many: Link Tables
    • A) Unidirectional One-to-Many Association with link table
      • Sample 6 — One-to-Many: Unidirectional Link Table
    • B) Unidirectional Many-to-One Association with link table
      • Sample 7 — Many-to-One: Unidirectional Link Table
    • C) Bidirectional One-to-Many Association with link table
      • Sample 8 — One-to-Many: Bidirectional Link Table

• C. Mapping Many-to-Many Associations

  • C1. Many-to-Many: Link Table
    • A) Unidirectional Many-to-Many Association: User as Owner
      • Sample 9 — Many to Many Unidirectional Link Table (user owning the relationship)
    • B) Unidirectional Many-to-Many Association: Email as Owner
      • 010 — Many-to-Many: Unidirectional Link Table (email owning the relationship)]
    • C) Bidirectional Many-to-Many Association (with owner)
      • 011 — Many-to-Many: Bidirectional Link Table (with owner)]
    • D) Bidirectional Many-to-Many Association (without owner)
      • 012 — Many-to-Many: Bidirectional Link Tables (without owner)
