Open Source C Database Engines/Servers

Uniform Server is a free lightweight WAMP server solution for Windows. Build using a modular design approach, it includes the latest versions of Apache, MySQL or MariaDB, PHP (with version switching), phpMyAdmin or Adminer. No installation required! No registry dust! Just unpack and fire up! ------- Note: The latest version of Uniform Server requires a **64-bit version** of Windows. -------

libdbi implements a database-independent abstraction layer in C, similar to the DBI/DBD layer in Perl. Writing one generic set of code, programmers can leverage the power of multiple DBs and multiple simultaneous DB connections by using this framework.

GT.M[tm] is a vetted industrial strength, transaction processing application platform consisting of a key-value database engine optimized for extreme transaction processing throughput & business continuity.

Virtuoso is a scalable cross-platform server that combines Relational, Graph, and Document Data Management with Web Application Server and Web Services Platform functionality.

SQLite.org took over this project in 2010

RedBlack balance tree searching and sorting library

A set of libraries and utilities for reading Microsoft Access database (MDB) files. THIS PROJECT HAS MOVED TO GITHUB: https://github.com/mdbtools/mdbtools

A free simple ADO.NET compliant MySQL driver. Made in C# but it would be used in all .NET compatible languages.

The libdbi-drivers project maintains drivers for the libdbi database abstraction layer written in C. Drivers are distributed seperately from the library itself.

Implementation of ANSI Standard MUMPS 1995 and ISO/IEC 11756 for FreeBSD, OSX and linux. Also on the Raspberry Pi (ARM) under debian and Windows under cygwin. This is the post-relational database.

Object-Relational Main-Memory Embedded Database system tightly integrated with C++ language. Use OS virtual mapping mechanism to access data. Provides subset of SQL language with OO extensions. Support of transactions, fault tolerance, replication.

An Integrated Development Environment (IDE) for the ESI Objects language (object-oriented MUMPS) that works on linux and, eventually, other UNIX-like Operating Systems.

The Malete database core is the new basis of OpenIsis, which has its roots in the UNESCO CDS/ISIS database. Traditionaly used in libraries; now a general purpose highspeed database.

Personal AMP - Apache, MySQL and PHP - stack for the S60 mobile phone. For installation and other information, please follow the 'Project Web Site' link to the right, or Project->Website from the menu.

Leto is a multiplatform database server or a database management system, chiefly intended for client programs, written on Harbour, be able to work with dbf/cdx files, located on a remote server.

Tokyo Cabinet is the successor of QDBM, a high performance database library similar to the DBM family. It also supports hash and B-tree databases and does not require any server process. The overall speed is improved compared to QDBM.

LifeLines is a genealogy program to help with your family history research. Its primarily strengths are its powerful scripting language and the ability easily import and export information in the GEDCOM format.

Windows CE port to the SQLite library (see http://www.sqlite.org).

Postgres-XC is a write-scalable synchronous multi-master PostgreSQL cluster with the following features. 1) Both read and write scalability. 2) Configured with more than one server. 3) Complete global transaction and visibility management.

ConceptBase.cc is a multi-user deductive and object-oriented database system for metamodeling and method engineering. Includes a graphical client that builds upon the logic-based features of the ConceptBase.cc server. The data model is O-Telos. ConceptBase.cc can represent information at the data level (example data, traces of process executions etc.), the class level (schemas, process definitions etc.), the metaclass level (constructs of modeling languages), the meta-metaclass level (constructs for defining modeling languages), and so forth. ConceptBase.cc is developed by the ConceptBase Team at University of Skövde (HIS). ConceptBase.cc supports Linux, Mac OS X and Windows. ConceptBase.cc is free software distributed under a FreeBSD-style license.

FLAG was designed to simplify the process of log file analysis and forensic investigations. FLAG facilitates efficient analysis of large quantities of data within an interactive environment. PyFlag is the reimplementation of FLAG in Python.

From pg_statsinfo 14, pg_statsinfo and pg_stats_reporter have moved to Github. See Github for information on later versions. See Sourceforge for information on pg_statsinfo 13 and earlier. pg_statsinfo : https://github.com/ossc-db/pg_statsinfo pg_stats_reporter : https://github.com/ossc-db/pg_stats_reporter ------- pg_statsinfo is a utility that monitors statistics and activities of PostgreSQL. pg_statsinfo is easily installed then periodically stores snapshots, which consists of activity information of PostgreSQL server and some information about system resources, into repository. These snapshots are visually examined using pg_stats_reporter, dedicated web-based visualization tool for pg_statsinfo. The tools make health checking or activity analysis of server easier for PostgreSQL DBAs. ------- pg_statsinfo project has been moved here from pg_foundry.

A relational database management system, based on the principles laid down in the book "Databases, Types, and The Relational Model: The Third Manifesto" by C. J. Date and Hugh Darwen.

Anastasia is a SGML/XML publication tool which allows the processing and searching of large documents using tcl scripting. See https://github.com/peterrobinson/Anastasia2 for updated code, etc, for running in Apache 2 environments.
