I honestly love SQLlite, so many things about this database are refreshingly amazing. The lightweight embedded nature, the extreme ubiquity[1], the single-source-file-to-compile idea[2], the gigantic test suite[3], their commitment to stability and backward compatability[4], etc ...

Simply a modern marvel of engineering. A thing to put on the next Voyager and send to aliens as a representative of what human minds and hands can do.
