Open Source Database Management Systems (DBMS)

MDO is an open source data-access component suite, providing direct access to Firebird from Borland Delphi applications. MDO is a descendant of FreeIBComponents by Greg Deatz, so IBX users looking for a migration path to Firebird can have a look at these

SQLite Micro Manager is a lightweight, fast and configurable GUI program mostly designed to access, browse and modify data in SQLite3 databases maintained by other applications, like Web browsers, home accounting software etc. It supports drag-and-drop operations, saving to and retrieving SQL statements from internal library and disk files. runs natively on 64 bit Windows 7/8/10 and Linux Ubuntu derivatives with GTK2+. Can be easily compiled for OSX and Linux GTK3 and QT widget sets with minimal changes. It can run without any installation, although proper installation packages are provided for Windows and Ubuntu-based Linux distributions. The intended audience is people with at least basic knowledge of SQL who need fast and simple tool to deal with SQLite3 databases.

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.

FOML is an expressive logic rule language that supports object modeling, analysis, and inference. It naturally supports model-level activities, such as constraints (extending UML diagrams), dynamic compositional modeling, analysis and reasoning about models, model testing, design pattern modeling, specification of Domain Specific Modeling Languages, and meta-modeling. FOML can reason about: 1. The model meta-data (meta-model level reasoning, or syntax reasoning) 2. Data level: reason about a model and its data (instance model, i.e., diagram) FOML is built as a semantic layer on top of PathLP - a compact logic rule language of guarded path expressions, an adaptation of a subset of F-logic.

Tracks project details using a variety of data options. Primarily designed to contain and organize software requirements in a multi-project, multi-user, environment using a networked SQL compliant database management system while tracking changes.

Command-line tool lets you copy table data from Oracle to SQLServer database. Touch and go design.

pyproperties provides support for properties files in Python. Being written entirely from scratch it is not in any way derived from java.util.Properties. There are projects which try to mimic j.u.P. This is not one of them. It can read, parse and store properties files but also provides some more advanced functionality like manipulating comments and type-guessing.

This is a small tool useful to update a database using a folder with sql script inside. To keep track of updates, a system table named XSB_UPDATES will be created. This table will be updated automatically after the execution of each script sql. Current supported database: - Firebird - Sqlite - Ms Sql Server Databases to test: - MySql - Postgres - Oracle - Sybase

Geeny is a scriptable game engine with built-in support for 2D graphics and sound. The scripting language is object oriented, high performance is attainable by using vector and array operations. Win32 C++, full portability planned in the future.
