Design/Reverse Engineer/Generate Scripts/Compare Versions of all major databases with "Apricot DB" ERD- tool "Apricot DB" is a database tool for design and analysis of the relational database structure. It represents the DB- structure in the form of editable Entity/Relationship Diagrams (ERD). "Apricot DB" allows to perform reverse engineering on the existing database, as well as to create a new database structure from scratch. Allows to generate the essential DDL- scripts for CREATE/DROP/DELETE- operations based on the current ERD. "Apricot DB" supports two popular ERD notations: the "Crow's Foot" and "IDEF1x". The databases supported by Apricot DB: Oracle; SQL Server; MySQL; MariaDB; PostgreSQL; DB2/DB2 LUW; H2; SQLite Your feedback is appreciated.

A component based programming framework. This project is aimed to support various target frameworks. A wxWidgets based GUI application is the major sample which also provides rapid database GUI design with UML import and export (db reverse engineering).

A web based tool to generate ERD (Entity Relationship Diagrams)

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.

Fourth generation database designer and code-generator for educational purposes and speeding-up database designing and creating work.

A graphical design tool for building a database schema. Connects to several live databases (including Postgres, MySQL, Sybase and MS SQL Server) and uploads and downloads schemas. Generates and parses SQL and generates Java source code from the schema.

KnowledgeFrame is a proven, mature Java framework for agile design and development of sophisticated business database applications based on live metadata and live business rules, using a declarative approach. Links to RETS 1.7 protocol.

PGExpert Student is a more basic tool full version, but with the same characteristics. Create database of integer data with this powerful tool for PostgreSQL.

(Pre-Alpha) Cross-Platform ERD to Database Design Tool built in Java. Currently Supports PostgreSQL. Not Feature-Complete.

The “RDB2RDF Mapper” is a Java based software desktop application which allows a user to create a mapping file between a relational database and an RDFS/OWL ontology via a graphical user interface. This project is ANDS-funded.

A set of framework to build business applications using j2ee stack. It's aimed to be customizable and full feature. The approach is model driven architecture.

SQLOrm focuses on mediating database interaction rather than shielding the user from it. SQLOrm consists of 3 major parts. A dynamic query builder. A prepared statement layer. A resultset to object graph mapper, supporting batch inserts/updates.

SchemaForms is a toolkit for building HTML form from an XML data file and an XML-Schema specification. Supports basic data types (string, checkbox, enumeration,..) but is easily extensible to custom data types.
