Java enterprise development with db4o
Java™ developers can get a lot of mileage out of storing objects directly in an object-oriented database like db4o. Without support for transactions or the ability to use data in a distributed environment (and keep it secure), however, you probably won't have much use for the OODBMS. In this final installment in The busy Java developer's guide to db4o, Ted Neward shows you how db4o handles three concerns central to Java enterprise development: transactions, distributed data management, and Web application security.
