data storm – a new free database viewer for TDD
Data Storm is a free open source data base browser. While there are millions of data base browsers freely available online, Data Storm is different as it can be launched directly from within your Java code. This enables you to see and modify data that otherwise may not be available to you (e.g. data that will be rolled back).
It is freely available from http://datastorm.sourceforge.net/motivation.html
which also motivates why you need the tool
