Jailer is a database subsetting and browsing tool. It is a tool for data exporting, schema browsing, and rendering. It exports consistent, referentially intact row-sets from relational databases. It removes obsolete data without violating integrity. It is DBMS agnostic (by using JDBC), platform independent, and generates DbUnit datasets, hierarchically structured XML, and topologically sorted SQL-DML.
pyxmdb is a database utility for exporting and importing data between a delimited text file (e.g. CSV) and virtually any DBMS. It has been tested with SQLite, MySQL, PostgreSQL, Oracle, and DB2. It supports running SQL statements before and after performing the import or export. Also allows for any of the SQL statements to be read from a file or provided on the command line. It supports reading and writing of compressed files, in addition to standard input and standard output.
Address Book Continued is a multi-user address book Web application. It also makes use of AJAX, which means that page reloads only happen on login/logout; the rest of the operations is handled asynchronously in the background. It's well usable, even over slow connections. You can even install ABC on your desktop PC and configure it so that it doesn't require login for connections coming from the local computer.
4Sports is an exercise management application. You can use it to analyze your exercises in a number of ways. 4Sports can import data from the Garmin "Forerunner 201/301" devices, and can display some information in a table and in a graph (like heart rate over distance). It's also possible to export the tracks (GPS data) into Google Earth, where the track is color-coded according to your heart-rate. The graphs can be exported to SVG files.
jguigen (Java GUI Generator) generates screens to do CRUD (create, review, update, delete) from tables in a database. It supports any major database using JDBC. It generates fully internationalized and accessible screens that allow users to search tables, run reports, and calculate summary stats. It generates multi-user safe screens with help buttons that work, generates test cases to test the generated GUIs, and generates HTML documentation about the GUIs generated.
