Simple Object Persistence with the db4o Object Database (14 tags)
Mapping Java objects to relational databases is a difficult task, fraught with perils and gotchas. db4o dodges the issue entirely by providing an object-oriented persistence mechanism that is small, lightweight and efficient. Jim Paterson shows how it works.

Standardizing Java Persistence with the EJB3 Java Persistence API (9 tags)
Dissatisfaction with entity beans as an "official" means of persisting Java objects to databases has prompted a number of "unofficial" approaches, such as the very popular Hibernate. Now EJB3 seems to have learned its lesson: its new Java Persistence API allows you to persist plain old Java objects (POJOs) with a minimum of fuss and just a few annotations. Debu Panda looks at how to put this new standard to work.

Hibernate Your Data (7 tags)
Hibernate can persist any kind of Java object, manipulate a hierarchy of objects, handle collections, and work with transactions. Davor Cengija shows you how.

Making the Most of JDBC with WebRowSet (7 tags)
Database to XML and back again. If everyone's doing some or all of this, then shouldn't we write it once, get it right, and standardize? JDBC 3.0's WebRowSet offers a profound increase in power over the old ResultSet. Sharad Acharya shows you what's possible.

Prevalence: Transparent, Fault-Tolerant Object Persistence (6 tags)
Want to persist your objects, with transactional integrity? You probably assume you're going to be using a database, but not so fast--for lighter uses, particularly for prototyping and testing, the idea of "prevalence" may make more sense. Jim Paterson introduces it by way of Prevayler, a popular prevalence framework.
