Collections and arrays for the busy Java developer
Collections and arrays introduce new levels of complexity to the structured objects first discussed in The busy Java developer's guide to db4o: Beyond simple objects. Fortunately, db4o isn't the least bit fazed by handling multiplicity relationships -- and neither should you be.
Transactions, distribution and security with Java db4o
Java developers can get a lot of mileage out of storing objects directly in an object-oriented database like db4o. Learn how db4o handles three concerns central to Java enterprise development: transactions, distributed data management, and Web application security.
