My name is Thomas Kellerer, I live in Munich, Germany.
SQL Workbench/J came into existance because I didn't want to learn a new SQL tool for every DBMS I had to use. I use this tool on a regular (daily) basis in my own work. I also wanted to have a tool that could do basic data migration between different kinds of DBMS systems.
If you have any suggestions on how to enhance the application, if you find a bug or if you are missing support for a DDBMS, feel free to write me an email.
I will try to add support (beyond what JDBC offers) for any DBMS that I have free access to (e.g. a free trial download).
Some of the DBMS specific support in the Database Explorer (e.g. display of stored procedure source, view source) can be configured without building a new distribution. If you have questions regarding this, feel free to write me an email.
