SuperQuaiL is a Java SQL query builder. The goal of SuperQuaiL is to help Java developers who code SQL run and create queries easier. Other database tools focus on making it easy to do database administration and it is nice to be able to inspect the database through these tools. PhpMyAdmin, for example, a is nice web front end that you can run from multiple computers, but the interface is clumsy for the developer. For development, building queries is the main task and having a small program that loads quickly is more helpful than having a complicated interface where you can find out almost anything about the database. SuperQuaiL provides nice features to aid in the process of developing queries quick and easy.
Scriptella is an open source ETL (Extract-Transform-Load) and script execution tool written in Java.

log4jdbc is a JDBC driver that can log SQL and/or JDBC calls (and optionally SQL timing information) for other jdbc drivers using the Simple Logging Facade For Java (SLF4J) logging system.
Generic Model Organism Database project, a collection of open source software tools for creating and managing genome-scale biological databases.
