The goal of any ORM (like Hibernate) is to abstract away the quirks and pain of interacting directly with the underlying relational database. And they do it very well! They do it so well, that you can almost forget about your RDB and shift your focus solely on building a beautiful object model. This works perfectly for a simple application, but when the codebase gets complex or you hit a performance issue you may have to brutally wake up.

To address these concerns, the Domain-Driven Design (DDD) Community building complex applications developed a series of best practices that we will cover in this session. In other words, we will cover many of the "technical tactics" that you can find in the DDD books, but without diving too deeply in the "true meaning" of DDD.

Among the things you will hear:
- Avoiding bidirectional links
- Limit relations via numeric ids
- ID Types (microtypes)
- Semantic IDs
- Decomposing large entities
- Enforcing Entity Consistency & Validation

As usual, please ask any question you want. Expect a highly interactive session.
