Open Source Code Generators

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.

DaoAnnotation is a Java projet to use simple dao CRUD with simple annotation.

J2J provides an intuitive way to convert Java to JSON and JSON to Java. Annotate any Java class then use JsonWriter to emit JSON from java or JsonReader to convert JSON to java objects. (source code and tutorial included) Version 2.0 in development.

JPA-XJC is a JAXB 2.1 XJC plugin for annotating schema derived classes with Java persistence annotations. It does not generate code depending on libraries other than JPA 1.0 and does not introduce non-standard customization elements.

Map My Data (MMD) is a code generator for Freepascal. It generates persistence classes that perform mapping between business objects and SQL statements.

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.

NHibernate.BusinessObjects is an easy to use business layer that wraps the object-relational mapper (ORM) NHibernate. NHBO is designed for Winforms and WPF applications. Visit http://nhbusinessobj.sourceforge.net to get more information.

QueryObjectFactory (QOF) is a lightweight runtime JDBC byte-code generator providing support for CRUD (create, retrieve, update and delete) operations and stored procedure calls. It uses Java annotations to define mappings and is fully OSGi ready.

A command line interface for creating and managing Apache iBatis mapping files.

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.

lunaORM is an ORM open source and freely downloadable automatic code generator to facilitate and standardize the writing of classes that read/edit/save data to database.

pdoMap is a robust PHP ORM mapper with many OOP features. The mapping structure, requests, and transactions are defined in XML files. The core directly generates PHP classes for high performance. It is very easy to use and configure.
