SQLite is a small and lightweight SQL database frontend, and can be very useful for a wide variety of tasks.

A binary compiled with DJGPP for DOS can be downloaded from iBiblio with the following URL:

http://www.ibiblio.org/pub/micro/pc-stuff/freedos/files/util/file/sqlitex.zip

The source code for SQLite can be found at its home page, http://www.sqlite.org; in order to compile the source code, use the following configure command:

./configure --prefix=/dev/env/DJDIR --disable-dependency-tracking --host=i386-pc-msdosdjgpp --target=i386-pc-msdosdjgpp --build=i386-pc-msdosdjgpp --disable-tcl CC=gcc

and change -DOS_WIN in the resulting makefile to -DOS_DOS.
