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.
Build around JDBC and XML, this tool allows you to maintain visual repesentations of a database's layout, edit table's data, generate code to bind objects to tables, and export data in XML format to easely export data from one database to another.
