Body
The Java EE components all run on the server side, either on full Java EE servers like GlassFish, JBoss, WebLogic, or WebSphere, or on servers like Tomcat that just support servlets and JSPs. In Java EE the MVC model can be thought of as a "domain model", ie the Java objects representing the entities that are important to your application. For instance a shopping application would have domain objects representing items for purchase, shopping carts, credit cards, mailing addresses, accounts, reviews, and so forth. Often these domain objects come from persistent storage such as a relational database. Java EE's Java Persistence API is designed to handle the mapping between the Java domain model objects and the relational database tables used to make the objects persistence. <a href="https://www.hibernate.org/397.html" rel="noreferrer">Hibernate</a> is one implementation of a JPA "object-relational mapper" (ORM). Java EE is much more than that. To take just one example, it defines an ultra-reliable messaging service (Java Message Service) that back end application components use to communicate with each other. As you explore Java EE, do give some thought to simpler and more productive alternatives like Ruby-on-Rails, LAMP stacks, Microsoft's .NET platform, and "light-weight" Java approaches like Spring/Hibernate. Richard Monson-Haefel, who wrote O'Reilly's very successful "Enterprise JavaBeans 3.0" (the fifth edition) and "Java Message Service", even goes so far as to <a href="http://podcast.burtongroup.com/ip/files/bgip_jee5_the_beginning_of_the_end.mp3" rel="noreferrer">claim</a> that Java EE is "intimidating" to developers and will be eclipsed by these other approaches. A good place to get a wider perspective is Todd Hoff's wonderful blog at <a href="http://highscalability.com/" rel="noreferrer">http://highscalability.com/</a>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
