User contributed components that extends the functionality of NHibernate. More information in the wiki: http://www.nhforge.org/wikis/. Development List: http://groups.google.com/group/nhcdevs

"Aubit 4GL" is a project to make GPL, OpenSource, Informix-4GL compatible compiler, and continue to extend functionality needed to write most efficient and productive business related, database oriented applications. See "Home Page" link for more.

Unify your data structures in XSD! XSD2DB Utility lets you manage database schemas using XSD files. Supports SQL Server and Jet databases. Can be extended to support other DB platforms. xsd2db requires .NET Framework 1.0

The Object-Role Modeling (ORM) standard version 2, associated schemas and generation tools, and a reference implementation in the form of the Natural Object-Role Modeling Architect for Visual Studio (NORMA) product.

openDBcopy is a universal database utility to migrate data from and to any database given a JDBC driver. Standard plugins are included, custom ones can be added. Complete migration job saved as XML for easy re-use. Run with GUI or as batch.

DBOW is a database compiler-compiler or front-end. It takes table definitions in a relatively high-level language and prepares C, C++, PHP, Perl (etc) functions for manipulating the database. It will also produce SQL table data for MySQL.

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.

MDExtractor extracts meta information from 1Cv7.MD (1S Enteprise v7) file and stores it in the database. Some ideas has been taken on http://www.mista.ru/ site and from "md2mdb" project.

BEEJ is a Boolean Expression Editor for Java. This library provides a GUI interface to build complex (or simple) expressions with your options as a base component.

Diaper, DIA Plugin for ER modeling is a tool which takes as input a Dia XML file describing a ER model and outputing SQL-92 standard statements. As of now, Diaper is one of few tools which is capable of handling several complex set of input ER models.

Jamaica is a simple and light but powerful utility to execute sql statements, scripts etc. written entierly in java.

.NET utility capable to automatically generate XML database schemas and then translating those to SQL scripts (both data import/export and stored procedures for data access) and C# wrapper classes.

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.

RDBS2J is a GUI based mapping tool from relational database schema to persistent java classes which use JDO as persistence mechanism. The mapping can be modified by the GUI. The current version is designed to create code for Apache-OJB.

Web-based Visual Query Designer is a tool for generating SQL queries. Currently, it is designed for MySQL only. Do checkout the demo from the project's website. [Note: Only SELECT queries, without GROUP BY (aggregation), can be designed.]

a framework library with a template method interface and inheritable classes for an executable process design which produces an executable which is both a GUI and a console application. It provides multi-threading for work items of the provider process .

The project aims to create a web based database administration tool, with expansion into automatic code generation from the database schema. The code allows creation and removal of databases, tables and fields via a web browser.

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.

Cartographer is a simple,efficient object relational mapper engine. It provides rapid access to relational data using lightweight data and factory java objects.

Welcome to Data Access Layer for Java (DAL4j) a set of command line tools and framework used to reverse engineer a MySQL or SQLServer database schema into a set of JPA Entity Beans. DAL4j can be useful for scenarios where there is an existing database schema but a technology other that JPA is used to interact with the database. DAL4j can provide an easy way to migrate your code base from other technologies such as JDBC or Hibernate to JPA. The beans generated can be 1 or two types: Simple or Framework. Simple beans are standard pojo classes managed by your application using JPA semantics. Framework generated pojos use the DAL4j framework DAO generic to simplify CRUD operations. DAL4j provides optional hooks to allow you to integrate encryption/decryption of data field used when data is encrypted in the database. Last, DAL4j provides a set of Generic classes that can be used to simplify creation of J2E Session Beans which perform CRUD operations using generated Entities

Dia2SQL is a Perl script to convert UML objects in DIA ( see http://www.lysator.liu.se/~alla/dia/ for more info on DIA ). Currently, it processes Dia documents exported as Encapsulated PostScript ( EPS ).

Datadump is an application for Creating DataDump Text File Along With SQL Script [Insert Statements] From Any Accessible SQL Server Database For Saving (Data Backup) And Restoring Data. Can Be Used For Uploading Data To Remote Server Using Query Analyzer

From the XML definition of your database, DewDrop will generate clean and human-readable SQL DDL code for any supported target database. This means you can define your database just once in XML, and have it work for any database automatically.

DruideDB is an embedded database (based on Object/XML mapping files) for Java applications. Both source code (DAO) and persistence layer (mapping) is generated. This DB stores everything as strings and handle auto-increments and multiple PKs.

Datawarehouse process workflow server and generator of datawarehouse mappings. It allows to define dependencies between tables or files and processes and according to these metadata it runs processes in parallel.
