SQL-at least.

I didn't mentioned a "micro kernel language"  yet - but in fact - that 
would be the idea. This is a relative simple language which can be 
parsed or interpreted very efficiently. An SQL parser then just 
translates from SQL to "micro kernel query" language - much like a C++ 
compiler translating into assembler.
(an SQL parser then could run on the client - which frees resources on 
the server!!)
