DESCRIPTION

KiokuDB is a Moose based frontend to various data stores:

• Berkeley DB
• SQL databases
• plain files
• CouchDB
• Amazon SimpleDB

Its purpose is to provide persistence for "regular" Perl objects with as little effort as possible, without sacrificing control over how persistence is actually done, especially for harder to serialize objects.

KiokuDB is also non-invasive: it does not use ties, AUTOLOAD, overloading, proxy objects or any other type of trickery.

KiokuDB is meant to solve two related persistence problems:

Transparent persistence

Store arbitrary objects without changing their class definitions or worrying about schema details, and without needing to conform to the limitations of a relational model.

Interoperability

Persisting arbitrary objects in a way that is compatible with existing data/code (for example interoprating with another app using CouchDB with JSPON semantics).
