I note a tremendous *lack* of symmetry!

Java, C#, C++, and Python are comparably expressive, and at comparable levels of abstraction. (I can hear the screams of the language advocates already.) Sure, Python has list comprehensions and C++ has a turing-complete generic type system, but they're all fundamentally imperative and procedural.

On the other side, you put together Oracle and flat files! Oracle has natural join; flat files have what exactly? seek()?!
