Trivial Persist was developed to provide the
quickest and easiest means possible to achieve
object persistence in Java. It uses neither XML
files nor SQL databases, and it uses normal Java
classes for access (such as Set, Comparator, and
Iterator) rather than JDBC or a new API. As a
result, a new object repository (called a Store)
can be created or modified in just a few seconds.
It is not designed for huge databases. The disk
storage format can be manipulated by simple text
processing tools.
