Oracle Berkeley DB is a family of open source embeddable databases that allows developers to incorporate within their applications a fast, scalable, transactional database engine with industrial grade reliability and availability. As a result, customers and end-users will experience an application that simply works, reliably manages data, can scale under extreme load, but requires no ongoing database administration. As a developer, you can focus on your application and be confident that Oracle Berkeley DB will manage your persistence needs.

ADOdb stands for Active Data Objects Data Base. ADOdb is a database abstraction library for PHP. The PHP version currently supports an amazing number of databases, thanks to the wonderful ADOdb community: MySQL, PostgreSQL, Interbase, Firebird, Informix, Oracle, MS SQL, Foxpro, Access, ADO, Sybase, FrontBase, DB2, SAP DB, SQLite, Netezza, LDAP, and generic ODBC, ODBTP. The Sybase, Informix, FrontBase and PostgreSQL, Netezza, LDAP, ODBTP drivers are community contributions.

MonetDB is an open source column-oriented database management system developed at the Centrum Wiskunde & Informatica (CWI) in the Netherlands. It was designed to provide high performance on complex queries against large databases, such as combining tables with hundreds of columns and multi-million rows. MonetDB has been applied in high-performance applications for data mining, online analytical processing, geographic information systems, XML Query (XQuery), text and multimedia retrieval.

DBIWrapper is a generic database Perl module for accessing the Perl DBI database interface. It provides the lowest level of functionality needed by any program wanting to access databases via the DBI. Currently, DBIWrapper is only aware of Pg (PostgreSQL), mysql (MySQL) and ODBC DBD modules and how to work with them correctly. Support for transactions on MySQL is now checked for and if found to be available, the AutoCommit flag is turned off so that transactions will be used.

PgDBF is a program for converting XBase databases - particularly FoxPro tables with memo files - into a format that PostgreSQL can directly import. It's a compact C project with no dependencies other than standard Unix libraries. While the project is relatively tiny and simple, it's also heavily optimized via profiling - routine benchmark were many times faster than with other Open Source programs. In fact, even on slower systems, conversions are typically limited by hard drive speed.

SOCI is a database access library for C++ that makes the illusion of embedding SQL queries in the regular C++ code, staying entirely within the Standard C++. The idea is to provide C++ programmers a way to access SQL databases in the most natural and intuitive way. If you find existing libraries too difficult for your needs or just distracting, SOCI can be a good alternative.

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). LICENSE: LGPL2 or later

This is a collection of basic c++ classes, used for devel/lfcxml and databases/cego and probably other applications. Many more details are available at:
