Squirrel database java client, i have recently found and used in my office. May be only a few people know about it.
Squirrel is an open source SQL java client for almost all the database [u only need to mention which is the DB to use and then provide the jar file of JDBC connector of that DB.]
Some features of it
1) You can directly click and edit the datas [no like aquastudio for oracle]
2) You can view the Entity relationship of the tables.
3) You can export all the datas/image/print.
4) Using is quite simple and well explained.
5) For almost all the OS as its in Java.
6) Check the supported DB [almost all which i heard].
7) And not to mention its free.
And many more features
I have myself used and found comfortable [used in mysql].Its easy to use.
