Serverless database

*note to mod. Didn’t know if this was the appropriate forum. Kind of broad post…

So I got a tricky request from my boss and I am looking for possible solutions to it at the moment.
I need an embeddable database that can interact with flash, and has an interface (that isn’t flash) that can run without a server. I am currently looking at SQLite. It has a flash wrapper that can be used to connect to it without some form of server side language… it seems.

Does it have, say a JS interface to edit the DB?

I am open to suggestions, but it can’t require the the use of servers or of software that needs to be installed…

Thanks a lot in advance for the help and advice.
