Sample Java/Spring Boot code accompanying the Geek Time 'DDD in Practice' course, demonstrating a leave-approval microservice designed with Domain-Driven Design. It illustrates aggregates, repositories, domain events, layered architecture, and inter-service communication with PostgreSQL persistence.

Use cases

• learn domain-driven design with a real Java codebase
• see how to structure a DDD microservice with Spring Boot
• understand aggregate roots, entities, and value objects in practice
• study domain event persistence and publishing patterns
• learn DDD layered architecture (domain, application, infrastructure, interface)
• reference example for splitting a monolith into microservices
• see DTO/DO/PO object conversion across layers

When to choose

• you are learning DDD and want a worked Java example
• you follow the Geek Time DDD course and need its companion code
• you want a reference for repository, factory, and domain event patterns in Spring Boot

When to avoid

• you need production-ready leave/attendance software
• you need a maintained library with a license and active support
• you work outside the Java/Spring ecosystem
