AnyEvent::CouchDB is a non-blocking CouchDB client implemented on top of the
AnyEvent framework. Using this library will give you the ability to run many
CouchDB requests asynchronously, and it was intended to be used within a
Coro+AnyEvent environment. However, it can also be used synchronously if you
want.
Its API is based on jquery.couch.js, but we've adapted the API slightly so that
it makes sense in an asynchronous Perl environment.
This class provides application developers with an abstraction class
a level away from DBI, that allows them to write an application
that works on multiple database platforms. The idea isn't to take
away the responsibility for coding different SQL on different
platforms, but to simply provide a platform that uses the right
class at the right time for whatever DB is currently in use.
DBIx::Log4perl is a wrapper over DBI which adds logging of your DBI activity
via a Log::Log4perl handle. Log::Log4perl has many advantages for logging
but the ones probably most attractive are:
The ability to turn logging on or off or change the logging you see without
changing your code.
Different log levels allowing you to separate warnings, errors and fatals
to different files.
MLDBM - store multi-level hash structure in single level tied hash
This module, intended primarily for use with DBM packages, can serve as a
transparent interface to any TIEHASH package that must be used to
store arbitrary perl data, including nested references.
It works by converting the values in the hash that are references, to their
string representation in perl syntax. When using a DBM database, it is this
string that gets stored.
This module provides a nearly complete wrapping of the Sleepycat C API
for the Database Environment, Database, Cursor, and Transaction
objects, and each of these is exposed as a Python Type in the
bsddb3.db module. The database objects can use different access
methods, btree, hash, recno, and queue. For the first time all of
these are fully supported in the Python wrappers. Please see the
document in developers' web site for more details on the types and
methods provided.
The official Python client for Riak.
Riak is a Dynamo-inspired key/value store that scales predictably and easily.
Riak also simplifies development by giving developers the ability to quickly
prototype, test, and deploy their applications. A truly fault-tolerant system,
Riak has no single point of failure. No machines are special or central in
Riak, so developers and operations professionals can decide exactly how
fault-tolerant they want and need their applications to be.
BDB is a set of classes implementing an interface to
Berkeley DB for the GNUstep and Mac OS X environment written in
Objective-C language. It is based on the C API of
Berkeley DB and offers an object oriented interface which relies on
classes and mechanisms offered by the Foundation library.
In its present state BDB just offers a reduced set of functionality of
Berkeley DB.

This library is a lightweight database abstraction layer designed to make
it simple to write high performance applications using SQL databases from
Objective-C.
The library consists of a semi-abstract superclass doing much of the work
and allowing extremely simple database specific bundles to be written to
talk to particular database servers. It comes with backend bundles for
Postgres, MySQL, and SQLite (plus an untested Oracle bundle).

Tokyo Tyrant is a package of network interface to the DBM called
Tokyo Cabinet. Though the DBM has high performance, you might bother
in case that multiple processes share the same database, or remote
processes access the database. Thus, Tokyo Tyrant is provided for
concurrent and remote connections to Tokyo Cabinet. It is composed of
the server process managing a database and its access library for
client applications.
For those either needing a dummy PostgreSQL database full of real
facts and data, or those who make frequent use of the CIA's World Fact
Book, this is the port for you: wfb2sql converts the WFB into SQL
inserts. Act now and get your copy of the WFB for free now! The
WFB is a public domain document that may disappear as fast as you do
after the black helicopters lock in on your location!!!!
