Open Source C++ Object-Relational Mapping (ORM) Software for Linux

LiteSQL is a codegenerator and C++ library that integrates C++ objects tightly to relational database and thus provides an object persistence layer. LiteSQL supports SQLite3, PostgreSQL, MySQL and oracle as backends.

This is my attempt at creating an API similar to pythons Elixir for interfacing with SQL databases in C++

A library providing object-relational mapping services for programs written in C++. IOPC2 can be used in one of the following stand-alone configurations: An ORM library, a database access library and a library providing reflection capabilities.

MSS Code Factory turns XML Business Application Models into source code by applying a knowledge base of expansion rule cartridges. Each cartridge of rules in the knowledge base defines the code to be produced for a particular language, tool, or combination thereof. A cartridge can also integrate the rules from other cartridges, so you can create a virtual cartridge that will produce all the code to support a given software stack that the rules provide. MSS Code Factory takes over the duties of the junior programmer on large database integration projects, whose primary task is to follow the templates provided by the application architect and senior systems analysts. If you can provide a template, it is usually possible to define rules to produce code following the template. The rules themselves use a General Expansion Language (GEL) XML syntax.

QsT SQL Tools - ORM system based on Qt 4.6.0 (and higher) to improve programming databases with Qt. QST has a little functionality to make simple SELECT, INSERT, UPDATE, DELETE and EXEC queries. It uses PostgreSQL but can be ported for other language

QtPersistence is a project to create an ORM library for Qt Users. It’s loosely based on ideas from both the Active Record and Data Mapper Ruby ORM projects.

QxOrm is a C++ library designed to provide Object Relational Mapping (ORM) feature to C++/Qt developers. QxOrm engine is based on a simple and non intrusive mapping function by class to provide : Persistence, Serialization, Introspection, Reflection.

TreeFrog Framework is a high-speed C++ MVC framework for developing Web applications.

YB.ORM is a tool for object-relational mapping (ORM) for C++. Inspired by things like Hibernate or SQLAlchemy. Should be database-independent. Includes a tool for code generation of Domain objects. Tables' metadata description is an XML file.

The Chilon Library is a C++0x utility library. The most advanced parts are a command-line argument parser and a parser generator library based on parsing expression grammars with built in AST generation abilities.
