Hibernate simplifies inheritance mapping.

Learn three easy-to-implement strategies to map class hierarchies. Hibernate is an object-relational mapping and persistence framework that provides a lot of advanced features, ranging from introspection to polymorphism and inheritance mapping. But mapping class hierarchies to a relational database model might prove somewhat difficult. This article covers three strategies that you can use in your everyday programming to easily map complex object models to relational database models.

Overview

Our supporting example

Strategy 1: One table per subclass (Persons)

Strategy 2: One Table per class herarchy (Rights)

Database model integrity

Strategy 3: One table per concrete class (Estates)

Hibernate is an object-relational mapping and persistence framework that provides a lot of advanced features, ranging from introspection to polymorphism and inheritance mapping. But mapping class hierarchies to a relational database model might prove somewhat difficult. This article covers three strategies that you can use in your everyday programming to easily map complex object models to relational database models.

Overview
Hibernate is a pure Java object-relational mapping and persistence framework that allows you to map plain old Java objects to relational database tables using XML configuration files. Using Hibernate can save a lot of development time on a project, since the whole JDBC layer is managed by the framework. This means that your application's data access layer will sit above Hibernate and be completely abstracted away from of the underlying data model.

Hibernate has a number of advantages over other similar object-relational mapping approaches (JDO, entity beans, in-house development, and so on): it's free and open source, it has achieved a good level of maturity, it's widely used, and it has a very active community forum.

To integrate Hibernate into an existing Java project, you'll need to walk through the following steps:

Download the latest release of the Hibernate framework from the Hibernate Web site. (See the Resources section below for a link.)


Copy the necessary Hibernate libraries (JAR files) to your application's CLASSPATH.

Create the XML configuration files that will be used to map your Java objects to your database tables. (We'll describe that process in this article.)

Copy the XML configuration files to your application's CLASSPATH.
