INPRG94

DATES:

1. Configuring Hibernate
   • Specify database connection parameters, caching, and the collection of persistent classes managed by Hibernate.
   • Create a basic hibernate.cfg.xml file.
2. O/R Mapping
   • Building mapping definition files to provide Hibernate with information about persistent classes.
   • Specify advanced Hibernate configuration; this will need to include object caching and transaction management.
3. Manipulating and Querying Persistent Data
   • Use the primary Hibernate classes to persist and retrieve classes.
   • Create persisting class hierarchies - inheritance with Hibernate.
4. HQL: Hibernate Query Language
   • Assign aliases to associated entities or to elements of a collection of values using a join.
   • Reference the identifier property of an entity.
   • Pick the objects and properties which will be returned in the query resultset.
5. Performance and Best Practices
   • Write fine-grained classes and map them using component.
   • Identify natural keys.
   • Load mappings as resources.
   • Use bind variables.
6. Collections and Performance
   • Declare persistent collection-valued fields as an interface type.
   • Create collection instances which are distinguished in the database by the foreign key of the entity that owns the collection.
7. Cache
   • Use JBoss Cache as a Hibernate second level cache.
8. Persistent Classes
   • Create a class to table mapping of the supplied data.
9. Working with Persistent Objects
   • Code for persistent object updates and automatic dirty checking.
10. Inheritance
    • Develop an inheritance mapping strategy.
11. Transactions and Concurrency
    • Configure the Hibernate transaction for maximum concurrency.
