PARD: Data Bases
Interbase is a high performance multi-generational SQL database and it's now
available for free download. This is a professional quality database engine
with strong hooks into Borland's Delphi product and others. A basic perl
interface is available that does not comply with the DBD/DBI standard, but
is pretty functional.
LEAP is a free relational database management system (RDBMS) that is used by
an increasing number of universities around the world as a part of their
database courses. LEAP fully supports the relational algebra, and the
behavioural components of the relational model. It is intended as a teaching
tool and foundation for further work.
Mini SQL, or mSQl as is it often called, is a light weight relational
database management system. It has been designed to provide rapid access to
data sets with as little system overhead as possible. The system itself is
comprised of a database server and various tools that allow a user or a
client application to communicate with the server.
MySQL is a SQL database server designed for speed. MySQL is a client-server
implementation that consists of a server daemon mysqld and many
different client programs/libraries.
NoSQL is a fast, portable, relational database management system without
arbitrary limits, (other than memory and processor speed) that runs under,
and interacts with, the UNIX Operating System.
It uses the Operator/Stream DBMS paradigm described in "Unix Review", March,
1991, page 24, entitled "A 4GL Language". There are a number of
operators that each perform a unique function on the data. The
stream is suplied by the UNIX Input/Output redirection mechanism.
Therefore each operator processes some data and then passes it along to the
next operator via the UNIX pipe function. This is very efficient as UNIX
pipes are implemented in memory. NoSQL is compliant with the "Relational
Model".
PostgreSQL is a robust, next-generation, Object-Relational DBMS (ORDBMS). It
is not completely ANSI SQL compliant, but with each release it gets closer.
FreeTDS is an open source implementation of the TDS (Tabular DataStream)
database client access protocol and related libraries used by Sybase and
Microsoft. FreeTDS supports versions 4.2, 4.6, and 5.0 of the protocol, and
it supports DB-Lib, CT-Lib, and ODBC libraries.
WIDD is a client application to develop Databases with an X11 interface. In
fact WIDD replace psql for example in postgresql package. WIDD can be use
with all database conform with sql3/sql92 (as postgresql, mysql) with JDBC
drivers.
DBD-Pg is a PostgreSQL interface for Perl5 using DBI.
DBperl is a database access Application Programming Interface (API) for the
Perl Language. The DBperl API Specification defines a set of functions,
variables and conventions that provide a consistent database interface
independent of the actual database being used.
This program uses the Gtk GUI library to interface to a PostgreSQL DBMS.
GtkSQL is an interactive query tool for PostgreSQL. Its main feature are
multiple SQL buffers, SQL keywords, table names and fields autocompletion,
easy displaying of tables definitions as well as exporting of query results.

The Postgres Access System is a web interface that allows users to view and
submit items into a database that is on their system.
This page is a tutorial of the Structured Query Language (also known as SQL)
and is a pioneering effort on the World Wide Web, as this is the first
comprehensive SQL tutorial available on the Internet. SQL allows users to
access data in relational database management systems, such as Oracle,
Sybase, Informix, Microsoft SQL Server, Access, and others, by allowing
users to describe the data the user wishes to see. SQL also allows users to
define the data in a database, and manipulate that data. This page will
describe how to use SQL, and give examples. The SQL used in this document is
"ANSI", or standard SQL, and no SQL features of specific database management
systems will be discussed until the "Nonstandard SQL" section. It is
recommended that you print this page, so that you can easily refer back to
previous examples.
