libpqxx

libpqxx is a front-end for writing C++ programs that use PostgreSQL. It supersedes the libpq++ interface.

ADODB

ADODB is a set of advanced PHP database abstraction classes.

Supports open source databases: And others:
  • Informix, Sybase
  • SQL Anywhere,
  • Oracle, MS SQL 7 and 2000,
  • SAP DB, Sybase,
  • DB2, FrontBase,
  • Foxpro, Access,
  • Netezza, LDAP,
  • ODBTP, ADO,

and generic ODBC.

Ruby/DBI

Ruby/DBI – a database independent interface for accessing databases – similar to Perl’s DBI.

QLime

QLime is an easy to use Python library that enables object-oriented access to data residing in various sources (most notably relational databases). It includes an Object Relational Mapper.

kinterbasdb

KInterbasDB is Python DB-API 2.0 compliant interface for Interbase and Firebird (IB Phoenix) relational database systems.

Og (Object Graph)

Og (ObjectGraph) is a powerful object-relational mapping library. Og provides transparent serialization of object graphs to a RDBMS backend. Unlike other similar libraries Og maps standard Ruby objects to SQL tables and not vice versa. Og provides a meta language to describe the relations between objects, a flexible and intuitive api for querieng the database, raw access to the SQL language if needed (for example to fine tune the automatically generated SQL tables, or for custom queries), suports deserialization to Ruby objects or tuples, automatically generates join tables for many_to_many relations and provides a collection of usefull Mixins to synthesize common Entities.

Og is a combination of the best features of Active Record and the former O-R mapping library included in Nitro (NDB). Adapters for PostgreSQL, MySQL and SQLite are included.

Og is part of the Nitro project, released as a stand-alone library due to popular demand. You can find the ChangeLog in the Nitro distribution (nitro.rubyforge.org).

Bizgres

Bizgres is a database server built on PostgreSQL that focuses on Business Intelligence and Data Warehousing.

Bizgres distinguishes itself from a vanilla distribution of Postgres by optimizing for OLAP and offering features such as integration with JasperReports.

Bizgres binaries have been compiled for Linux, Mac OS X, and Solaris.

hsqldb

hsqldb is a relational database engine written in Java with a JDBC driver that supports a subset of ANSI SQL3.

PostgreSQL

PostgreSQL is a Object-Relational DBMS supporting almost all SQL constructs, including subselects, transactions, and user-defined types and more. The name comes from the fact that many of the original developers also worked on Ingres, and so this is the “post-ingres” database. Design for the system began in 1986, with an explicit goal of providing a database that completely supported types with the minimum number of features necessary. By the early 1990s, the database had reached a significant number of users. Around this time, its status as a University of California, Berkeley project ended, but due to the open source license, development continued, as it does to this day.

PostgreSQL is seen as the most popular open source database after MySQL, although it has in many ways more advanced and more mature implementations of key features, particularly those required by heavy-duty OLTP applications.
