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

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

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

RedBlack balance tree searching and sorting library

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.

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.

An ultra-lightweight Python interpreter that runs with only 4KB of RAM, and zero dependencies. It is ready to use out of the box without any configuration required and easy to extend with C. Similar projects: MicroPython, JerryScript.

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

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.

We humans are bound by intellectual abilities. All knowledge is far beyond power of any person. The only way to apply knowledge is to build machines able to present it human way but not limited by volume. Intellect Modeling Kit (IMK) is intended to build knowledge machines (KM) assisting experts on the steps of activity: * Observation; * Producing propositions based on knowledge; * Elimination of impossible propositions; * Selection and verification of the most appropriate propositions; * Memorizing - new knowledge item creation; * Abstraction – building objects representing typical signs of similar objects groups, data mining. KM is not intended to replace human experts, it is built to multiply abilities. Machine should not be responsible for decisions. The IMK is designed to create ready-to-use software applications using simple text files. Any human knowledge can be uploaded to KM by expert not familiar with software coding. Demos present in kit. Good luck!

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

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.
