Data Storm is a database browser that can be
embedded in Java code. It is intended to be used
within tests to allow you to inspect why database
dependent tests are failing. It uses SWT for speed
and native look and feel.
JDBC Logger is a tool that intercepts and logs all
database statements that use JDBC. It is intended
for developers to monitor SQL statements generated
by EJB, Hibernate, or any other database access
tool that doesn't display them in clear.
