|
* association, inheritance, polymorphism, composition
|
||||||
|
* and the Java collections framework. The Hibernate

|
* Query Language, designed as a "minimal"
|
||||||
|
* object-oriented extension to SQL, provides an
|
||||||
|
* elegant bridge between the object and relational
|
||||||
|
* worlds. Hibernate also allows you to express queries
|
||||||
|
* using native SQL or Java-based Criteria and Example
|
||||||
|
* queries. Hibernate is now the most popular
|
||||||
|
* object/relational mapping solution for Java."
