Oracle SQL Developer

Oracle SQL Developer is an alternative to the new web based interface for being able to explore a database. I think we used to call this "Management Studio" or something.   It has a pretty nice interface for being able to issue SQL statements, view tables and views, and create tables and the like. The standard web based interface (which I think is new with 11G) seems to not work if the IP address changes. Jen Baxter has more information on this.
