db4o - What a Concept

Neward gives a great summary of the long RDBMS slog so many developers have had to deal with, and what sounds like a very promising answer (db4o, which I haven't tried out yet):

I haven't been particularly fond of the QL variants / query object trees one has to create in Java when using, for example, Hibernate. Wonderfully, db4o apparently lets you code 'native queries,' which are basically anonymous inner classes with a match method, where your query matching logic is simply a normal java expression on whatever objects are relevant to the query. So QL statements like "select blah from person p where name = ? and age > ?" becomes something like:

match (Person p) {
return (p.getName().equals("name to match") && p.getAge () > 21);
}
