| Description |
Hibernate
is an open source object/relational mapping framework
for Java. It is
lightweight, yet powerful enough to relieve the
developers from most of the manual
work otherwise needed in handling data persistence.
This course covers all aspects of using hibernate
in developing Java relational
persistence applications, from configuration, defining
mappings, writing complex
queries, to employing best practices.
At least 60% of the time will be devoted to labs. |

Upon completion, students will be able to:
- Understand the Hibernate framework architecture
- Write Hibernate configuration file
- Write Hibernate mapping files
- Define persistence classes
- Write queries with Hibernate Query Language
(HQL)
- Learn best practices in using Hibernate to
build real world applications
