PostGIS adds support for geographic objects to the PostgreSQL
object-relational database. In effect, PostGIS "spatially enables"
the PostgreSQL server, allowing it to be used as a backend spatial
database for geographic information systems (GIS), much like ESRI's
SDE or Oracle's Spatial extension. PostGIS follows the OpenGIS
"Simple Features Specification for SQL" and has been certified as
compliant with the "Types and Functions" profile.
PostGIS development was started by Refractions Research as a project
in open source spatial database technology. PostGIS is released
under the GNU General Public License. PostGIS continues to be
developed by a group of contributors led by a Project Steering
Committee and new features continue to be added.
PL/Lua is an implementation of Lua as a loadable procedural language
for PostgreSQL: with PL/Lua you can use PostgreSQL functions and
triggers written in the Lua programming language.
forgetSQL is a Python module for accessing SQL databases by creating classes
that maps SQL tables to objects, normally one class pr. SQL table. The idea is
to forget everything about SQL and just worrying about normal classes and
objects.
py-leveldb is a thread-safe Python bindings for LevelDB. It has all features
from the LevelDB API, except for:
- Arbitrary key comparison
- Snapshots
- All iteration except for single-step forward
The python-rrdtool provides a interface to rrdtool, the
wonderful graphing and logging utility. This wrapper
implementation has worked from the scratch (without SWIG),
and it's under LGPL.
GNU Data Access (GDA) is an attempt to provide uniform access to
different kinds of data sources (databases, information servers,
mail spools, etc).
It is a complete architecture that provides all you need to access
your data, defined by a set of CORBA interfaces as generic as possible
(but very powerful at the same time) so that any kind of data source
can be accessed through them.
libgda is an interface to the GDA architecture, providing a nice
wrapper around the CORBA interfaces, for both the client and the server
parts. It also provides a bunch of tools to help you both in the
development and management of your data sources, all done through
the GDA model's set of CORBA interfaces.
libgda was part of the GNOME-DB project, but has been separated from it
to allow non-GNOME applications to be developed based on it.

A simple utility to merge existing RRD data from backups into new RRD files
that have started gathering data already. Useful for getting historical data
back while performing disaster recovery.
ActiveRecord-JDBC is a database adapter for Rails' ActiveRecord component
that can be used with JRuby.
It allows use of virtually any JDBC-compliant database with your
JRuby on Rails application.
Ruby DataObjects driver for MySQL
The purpose of DO.rb is to rewrite existing Ruby database drivers to conform to
a single interface.
At present, PostgreSQL, MySQL, and SQLite adapters are available.
