Berkeley DB is widely used, so might be a good choice...

XML is commonly found in the real world, and the data files are
portable. So, it's worth wrapping your hands around. The "GNOME"
libxml is very nice, and overhead can be minimized by using the SAX
interface (a little more complicated...).
For speed, you probably can't beat a binary file. But it's more
work to make it portable (endian issues, data type sizes, etc...).
If your C or C++ is rusty, I'd strongly suggest just using simple
text files so you can focus on what the program is supposed to do.
Later you can muck with file storage formats to balance speed, size
and portability. Abstract the file I/O from the rest of the program
so it doesn't need to care if the file format changes.
