XMLToaster is a tool for extracting and loading XML from databases. It provides a modified version of SQL which has XML mapping extenstions. It can be compared to the "for xml" command in MS SQL Server 2008, but it runs on all common databases and scales to handle very large XML mappings without too much complexity. It is used as a Java library to write XML interfaces, but can also be run as a command line tool.
StelsCSV is a JDBC driver that allows performing SQL statements and other JDBC operations upon text files (comma separated, tab-separated, fixed length, etc.). Using this driver, users can easily create a simple database consisting of plain text files. The driver can be used for writing data importing programs and migration tools. It supports most keywords of ANSI SQL92, table joins, INSERT, UPDATE, and DELETE statements, data types, aggregate, converting, string, and user-defined SQL functions.
naarani Personal Access is a Java library to run programs that need to create, design, and access a MySQL database. It features automated managment of user rights, SQL code, table updates/track, data input/user masks, and a plugin to quickly add menu/custom fields management. Table and modules (masks) can be created or updated while debugging (even inside Eclipse) without reloading the program.
FireStorm/DAO is a Java Code Generator that can import existing database schemas (from a SQL script or from a live JDBC connection) and can then generate a complete persistence tier. It generates Java source code and configuration files that developers would otherwise have to write by hand, and that is compliant with the Data Access Object (DAO) design pattern.
