JDB is a package of commands for manipulating flat-ASCII databases
from shell scripts. JDB is useful to process medium amounts of data
(with very little data you'd do it by hand, with megabytes you might
want a real database). JDB is very good at doing things like:
* extracting measurements from experimental output
* re-examining data to address different hypotheses
* joining data from different experiments
* eliminating/detecting outliers
* computing statistics on data (mean, confidence intervals,
histograms, correlations)
* reformatting data for graphing programs
Rather than hand-code scripts to do each special case, JDB provides
higher-level functions.
JDB is built on flat-ASCII databases. By storing data in simple text
files and processing it with pipelines it is easy to experiment (in
the shell) and look at the output.
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.

This module is the Sybase extensions to Ruby.
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.
The sql package adds the command sql to tcl. The author's intention is
to build generic database interface for TCL, but currently he only
supports MySQL.

pyPgSQL is a package of two modules that provide a Python DB-API 2.0 compliant
interface to PostgreSQL databases. The first module, libpq, exports the
PostgreSQL C API to Python. This module is written in C and can be compiled
into Python or can be dynamically loaded on demand. The second module, PgSQL,
provides the DB-API 2.0 compliant interface and support for various PostgreSQL
data types, such as INT8, NUMERIC, MONEY, BOOL, ARRAYS, etc. This module is
written in Python.

DB Browser for SQLite is a light GUI editor for SQLite databases,
built on top of Qt. The main goal of the project is to allow
non-technical users to create, modify and edit SQLite databases
using a set of wizards and a spreadsheet-like interface.
This project has previous been known as "SQLite Browser" and "Database
Browser for SQLite". "DB Browser for SQLite" will hopefully be the
name that sticks. :)
DBConnect (Database Connect) API is an easy to use C++ object API to allow
applications to connect to databases. Your DB applications can now become
cross platform and cross databased.
The API currently implements MySQL, Oracle8 and PostGreSQL drivers in the
Unix environments and MySQL, Oracle8 and ODBC in the Windows environment.
