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.

That's a really good idea, and since anything other than some equivalent to SQL tends to be unwieldy, scheme or lisp is the only language you can write it in.

I think various commenters are right that you should find an existing engine to extend.  Really what you want I think, is a collection of lisp macros that will call *any* database.

That solves what for me is the more interesting problem.  Running a db engine in your own process is probably trivial as long as you have access to the source.
