I switched to using an in-memory H2 database for development. It works great, but I'm not able to see my changes as I make them.
This is their suggested list of tools: http://h2database.com/html/links.html#tools
I tried DB Visualizer and SQL Developer, but I can't find the tables my software creates. Are there any gotcha's that I should be aware of when working with H2, or any suggestions on a nice tool for Linux.
