1. Flashback.
Kick off this training with a quick Hello World example to refresh Hibernate
basics, then delve into more advanced topics.
2. Advanced class and property mappings.
Have a look at the different mapping metadata facilities available for and in
Hibernate. Explore the standard XML mapping files as well as XDoclet and JDK 1.5
Annotations for EJB persistence. Hibernate's mapping type system is an important
supporting feature for fine-grained Java domain models, and you'll learn how
best design your persistent classes. Investigate the built-in mapping strategies
for entities, simple value types, and class inheritance, and explore custom
extension of the Hibernate type system.
3. Associations and collections.
Complex associations between entities, single-valued and with collections,
often require advanced Hibernate mapping knowledge. Discover various kinds of
mappings, as well as Hibernate's fully polymorphic behavior, and then apply this
knowledge in a lab exercise.
4. Transactional processing.
Hibernate defines several object states and provides APIs to change the state
of an object. Learn to use these APIs correctly, even in tricky situations. Use
Hibernate data filters to access regional and temporal data, and investigate
more advanced transaction processing concepts around optimistic locking,
pessimistic locking, and long-running application transactions.
5. Querying and fetching data.
Learn advanced object retrieval options and the correct usage of Hibernate's
association fetching strategies. Explore the new Criteria and Example API as
well as advanced HQL, EJB-QL (using the new EJB 3.0 persistence API), and native
SQL queries. The lab includes exercises around loading and storing objects
efficiently.
6. Application design.
A popular part of the Hibernate training, this section shows you how to
design and implement a persistence layer using Hibernate. You will learn to
correctly handle SessionFactory and Session in two-tiered and three-tiered
applications and the best practices for transaction handling. You will implement
event interception in the persistence layer for audit logging and other special
cases, and you'll explore Hibernate's data conversion capabilities for automatic
XML marshaling and the representation of domain objects in nested HashMaps.
7. Legacy system integration.
Many Hibernate developers must work with existing database schemas and
existing data. Unfortunately, these schemas usually are not in the best shape,
and the data might be difficult to map to Java objects. Discover reverse
engineering using the Hibernate toolset as well as advanced
Hibernate mapping techniques, such as formula-based mappings, natural and
composite keys, and triggers.
8. Deployment and administration.
Getting Hibernate up and running is usually very easy, and deployment
requires only a single configuration in most cases. Learn more advanced
configuration options and tricks, including deployment of Hibernate as a JMX and
JCA service in J2EE environments. Once your application is deployed,
administration becomes an important issue. You will learn how to use logging
efficiently and how to detect performance issues using runtime monitoring with
the new statistics interfaces.
9. Tuning.
Optimize database access with the goal of executing the optimal SQL queries
in all situations. You will learn data caching basics and when to use caching.
Then enable Hibernate's dual layer caching system in the labs and the cache for
query results. |
