Advanced Hibernate

This session covers advanced Hibernate topics beyond simple object persistence including session management, object locking, detachment and versioning, lazy loading performance issues and query tuning, advanced O/R mapping support, legacy database considerations, and the Hibernate cache architecture.

So you've taken the plunge and decided to go with Object/Relational Mapping (ORM) in your application and have selected the leading Java ORM framework, Hibernate. At first everything is simple but you quickly discover things are not quite as simple as they seem. In this session we'll tackle some of the more complex topics in Hibernate. Some things we'll talk about, cry about, and (maybe) overcome include session management; session propagation; detached objects, versioning, and locking; lazy loading and performance tuning options in queries; legacy database support including composite keys, multi-table entities, and triggers; inheritance mapping and polymorphism in associations and queries; and the cache architecture. We'll also briefly touch on SQL queries, unit and integration testing, and model object validation.
