db module for simple desktop application?

[sneakyimp]

I have been approached about developing a desktop application that is going to need a simple SQL engine for storage and a few queries. The plan with this application is to distribute it for profit so I believe that's going to rule out any GNU license projects.

Can anyone recommend a good, simple database engine/library that is easy to incorporate into a desktop application? I expect I'll be writing it in C++ but am looking at some other possibilities as well. Ideally it would work on Mac and Windows but it's OK for this little thing if it only works on Windows.

Have a look at SQLite's licence.

I think SQLite qualifies admirably on the "simple SQL engine" and "easy to incorporate into a desktop application" part, especially since it is a rather portable C library that works well with C++. Its license, or lack thereof, makes it a good choice for your needs too.

THANKS for input. I will definitely check that out. I will also look into postgresql - it's published under BSD license which means I don't need to bother with source code inclusion yadda yadda.

I was thinking of suggesting Postgresql too, but although it is good, it is not quite the "simple database engine/library" that SQLite really is.
