I think that it is reasonable for JavaDB project to focus Web developers on such a database. And one thing about automatic (read: stress) testing is kind of tools for generating both database side test code & web scripting code (PHP 5, Java, etc.) testing code. Unit test frameworks is a good thing, - but all those database testing tools do not generate testing code, they execute binary stuff in memory from client side (read: performing stress). This is a big minus, huge one for Web developers. John
