Java Domain Modeling: Single Table Inheritance with JPA and Hibernate

Mapping object-oriented inheritance to relational databases can be challenging for developers. Understanding how to implement Single Table Inheritance allows you to maintain clean Java code while optimizing database performance. This text-only course guides you through the foundational concepts of domain modeling and object-relational mapping (ORM). You will learn how to represent class hierarchies in a single database table, configure inheritance strategies using JPA annotations, and write clean, maintainable persistence layers. What you'll learn: Understand the core principles of domain modeling and object-relational mapping; Configure Single Table Inheritance using JPA and Hibernate annotations; Implement discriminator columns to distinguish between different subclass entities; Apply modern Java features like pattern matching alongside entity hierarchies; Query inherited entities efficiently using Spring Data JPA repositories; Write robust integration tests to verify your database mapping and schema generation. You will start with the fundamental theory of inheritance mapping before moving into step-by-step written tutorials. Through clear code explanations, you will learn to configure, query, and test a complete single-table inheritance model. This course is designed for beginner-to-intermediate Java developers who want to improve their database design skills. No advanced database administration or Hibernate experience is required to begin. Start reading today to master inheritance mapping in your Java applications.
