Hibernate: Paving the Path for Queries

(Page 1 of 4 )

In the second part of our series on Hibernate, we will take a close look at its architecture and core classes. We will also cover the different types of queries possible in Hibernate. Finally, we'll use a real world example to illustrate our discussion.

Architecture is the blueprint that not only provides reference point at any stage of Software Development Life Cycle (SDLC), but also helps in understanding the hook points that can act as the basis for future enhancements. From a developer’s point of view, understanding the architecture of any framework would help him/her to make optimum use of the tools that the framework provides.

 Hibernate is no exception. It is possible to work with it even without understanding the architecture and the core classes, but it would be like searching for a location without having a map. Hence in this part I will be discussing the architecture and core classes along with covering the basics of querying the mapped objects.

The first section will cover the architecture of the framework and the details of core classes. The second section will detail the different types of Queries possible in Hibernate. The third and last section will use the mapping created in the last part to exemplify the different queries discussed in the second section. That’s the agenda for this discussion.
