Hibernate’s design goal is to relieve the developer from 95% of common data persistence-related programming tasks by eliminating the need for manual, hand-crafted data processing using SQL and JDBC.
However, unlike many other persistence solutions, Hibernate does not hide the power of SQL from you and guarantees that your investment in relational technology and knowledge is as valid as always.
As a JPA provider, Hibernate implements the Java Persistence API specifications and the association between JPA interfaces and Hibernate specific implementations can be visualized in the following diagram: Ultimately the application domain model is the central character in an ORM. Hibernate works best if these classes follow the Plain Old Java Object (POJO) / Java Bean programming model.
However, none of these rules are hard requirements.
Entities, by nature of their unique identifier, exist independently of other objects whereas values do not.Here we will introduce the essential Hibernate APIs.This will be a brief introduction; we will discuss these contracts in detail later.With the coming of JPA, most of this information is now defined in a way that is portable across ORM/JPA providers using annotations (and/or standardized XML format).This chapter will focus on JPA mapping where possible.
