database engine

hello

I am looking for a database engine that meets these requirements:

1. Provides an API that does not require passing commands as strings which are then parsed at runtime.
2. Runs in the same process as the client application. It's just a library.
3. Is under 600kb in size.

If nothing like this exists, I will write a minimal special purpose one for the bbs in r6rs scheme or common lisp.

Thanks for the link to Synchronet. Right now I'm aiming for a functional clone of shiichan that isn't a pile of shit (no offense shii) so I can host it without being vulnerable. But I'm not going to use any of that worse is better, parse-sql-strings-at-runtime-because-your-compiler-doesn't-have-a-turing-complete-preprocessor-that-can-transform-sql-strings-to-compiled-statements-at-compile-time shit.
