The busy Java developer's guide to db4o: Introduction and overview
This first article in a multipart series introduces db4o and explains why it has become an important alternative to today's relational databases. 		Articles 20 Mar 2007  
 
The busy Java developer's guide to db4o: Transactions, distribution, and security
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.

The busy Java developer's guide to db4o: Structured objects and collections
Object-oriented applications make considerable use of inheritance, and they frequently want to use that inheritance (or "is-a") relationship to categorize and organize objects within a given system. This can prove difficult in a relational storage scheme, which has no intrinsic concept of inheritance, but in an OODBMS, it's a core feature. In this installment of The busy Java developer's guide to db4o, discover the surprising ease (and power) of using inheritance as a core feature when creating queries in db4o.

The busy Java developer's guide to db4o: Arrays and collections
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. 		Articles 18 Sep 2007  
 
The busy Java developer's guide to db4o: Beyond simple objects
So far, creating objects and manipulating them in db4o looks pretty easy -- maybe a little too easy, in fact. In this article, db4o enthusiast Ted Neward shows you what happens when simple objects become structured ones (that is, objects that reference objects) and issues like infinite recursion, cascading behavior, and referential integrity come into play.

The busy Java developer's guide to db4o: Database refactoring with db4o
Refactoring Java code is far simpler than refactoring a relational database, but fortunately that isn't so much the case with object databases. In this installment of The busy Java developer's guide to db4o, Ted Neward introduces you to yet another advantage of his favorite object database: db4o simplifies refactoring to the point where it's almost trivial.

The busy Java developer's guide to db4o: Queries, updates, and identity
Whereas the RDBMS uses SQL as its principal mechanism for finding and retrieving data, an OODBMS can use one of several different mechanisms. In this second installment of his series, Ted Neward introduces a few of the options, including Query by Example and custom mechanisms unique to the OODBMS. As he explains, some of the alternatives can be easier to use than SQL itself. 		Articles 27 Mar 2007
