Open Source Database Engines/Servers

This project (licensed under LGPLv3) provides full documented procedures to build PostgreSQL from sources (and some additional extensions / Foreign Data Wrappers: sqlite_fdw, www_fdw, mysql_fdw, ldap_fdw, couchdb_fdw, oracle_fdw, odbc_fdw...) using MinGW-w64 (recent versions of gcc - 4.8.0 or later). It also provides ready made binaries/releases targetting Win32 as well as Win64 (Windows7). Note: Installers are also released to make easy the installation of the PostgreSQL extensions mentioned above in PostgreSQL installations made from the official Windows 7 - 32-bit and 64-bit - installers (those extensions releases - DLLs - being fully compatible with the said installers).

XML schema to specify relational database administration and operations. Uses XML, XSLT stylesheets and Java code to allow applications to use advance features of databases and have complex queries without being tied to a specific relational database.

Object Oriented Context Manager, serializer, editor API, targeted to extend short sized libraries able to play media objects as they are edited. Provides a virtual Machine, undo,merge,... API independant. Provides many extended libs. Demoscene oriented. https://www.youtube.com/watch?v=N86VfpYiz-Y

COMBuilder is a VB6 app that will allow you to write all COM objects for working with databases. Also, the program will create forms to work with this objects. It is planned to create also c# and vb.net code.

Intelligent e-knowledge base engine for any kind of knowledge-based applications, supporting effective knowledge presentation, precise knowledge search, adaptive learning and immediate consulting.

Model driven code generation can improve coding standards, speed, quality of development and reduce your costs. From my experience generating code from XML using XSLT is one of the best and fastest solutions. This is just the base of the framework presenting the idea, any code template can be implemented upon request. Some sample generators are present for SQL / PLSQL / C# / AnsiC / Java The main target is to generate DTO/BDO/POJO objects based on the database definitions in multiple languages aligning all technologies used by a development team. If you are willing to contribute drop a message.

PLNet.org is a repository of open source software that is written in PL/SQL or otherwise benefits PL/SQL developers. SourceForge hosts the "meta-project" for the repository tools: management, search, retrieval, update, and others.

C/C++/Java source code library and Build Environment. Contains code for threading, inter-thread communication (ITC), sockets, embedded database, parsing, fileio, etc. The majority of the library is designed for embedded development.

Data Evolution for Java. Finch is a Data Transformation System based on JDBC and other Java blessed specifications. Finch is based on a component task architecture allowing users to create complex data manipulation jobs.

The VPDM framework is a software engineering meta-model to allow encapsulated views to be superimposed onto schema. We can forward engineer systems using this approach.

Define your database structure and relations once using the ZsqlML (Zenark's SQL Markup Language) XML DTD, and then generate mulitple vendor-specific SQL scripts, thereby solving the issue of SQL script variances across multiple platforms.

A tool that extract a subset of a DB and create a smaller DB. Usefull tool for creating small DB for test/dev activity, starting from a real DB.

LIBOSO is Oracle database library, which implements some functions of SDO_GEOMETRY package. This library is written in C and is based on Oracle OCI and General Polygon Clipping Library made by Alan Murta http://www.cs.man.ac.uk/~toby/alan/software/

Open Source tools to be run in userspace

AMPPS is a stack of Apache, MySQL, PHP, Perl & Python. AMPPS enables you to focus more on using applications rather than maintaining them. With AMPPS you can create a website by installing any of the 330+ Apps, customizing it, and then simply publishing it on the internet via a wide choice of hosting service providers. A complete package on your desktop, same like the server that provides many open source web applications. Application Management, Domain management, Database management, etc are provided in a secure environment to ease your development. Softaculous is ready for your desktops with AMPPS to boost your development. Like servers, now auto-installation is possible on your desktop too. It provides your favorite script installations by the click of a button.
