I don't get your argument here. General purpose database software is
competitive in the sense that it is compared to other general purpose
database software. Not using such software may be orders of magnitude
faster than using it, depending on the purpose.

It would be simpler in the project sense rather than the lines-of-code
sense.

Those jar files are fairly large though. I work on a medium-sized
(250 KLOC) project which is about a 3 meg download. Adding the
necessary jar files from Derby would slightly more than double the
download size and load on our servers. We have lots of data that is
accessed by single keys only, which is stored in a custom
flat-files+index-files database. For efficiency, the data is organized
and accesses are cached in a very domain-specific way. Using
standard database software would be several times slower at best,
and the difference in speed would be noticeable to users.
