One of the greatest advantages of db4o
is that it works with plain old Java objects
(POJOs). I can avoid the large infrastructure
costs of relational databases such as schema
design. And db4o offers not only the advantage
of a small system memory footprint, but also the
advantage of a small 'developer memory' footprint.
The API is elegantly simple with a very short
learning curve."
