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.

Is this your first time creating anything with a SQL DB? You might want to get started:

If you want an awesome BBS already made look at Synchronet:

That need to be rewritten in in C and Scheme.
