Close to I-95 and Long Island Sound, across the river from New London, CT, and home to Electric Boat and Subase New London.
Electric Boat is the descendent of Holland Electric Boat, which built the first practical submarine, and is one of two yards (Newport News in Virginia is the other) still building US nuclear submarines. They built all the Trident submarines.
Subase New London is an attack submarine base (IIRC the USS Seawolf is based there) and is also home to the US Navy Submarine School.
The US Coast Guard Academy is close by. So is Mystic, CT, home to the Mystic Seaport, Mystic Marinelife Aquarium, and location of the file "Mystic Pizza".
It's a cute little area, but there's not much else around.
And, based on what Norm wants to do (brush up on DBA skills to improve his job skills), both Oracle and PostreSQL are better choices than IB.
