Why do starship databases contain such useless information? For example, in Flashback Janeway accesses logs from the Excelsior consisting of Sulu noting "routine maintenance" being done.
1) Wouldn't it make more sense for the ship's computers to access that from Memory Alpha or whatever?
2) Why is "routine maintenance" even considered interesting enough to be saved for 80 years?
I don't recall if it's from the TOS series or a novel or The Making of Star Trek, but the Enterprise computer was said to be the equal of the Federation's very best and had virtually infinite storage space. So why not cram absolutely everything in just in case a tiny tidbit became useful 100 years later?
(except for references to the Borg or the Ferengi or "holes in space" of course)
What might have been thought of as a useless tidbit, such as the 300 year old NASA code signal for Voyager to transmit its information sure became important in TMP. Its amazing that such data survived the both the Eugenics War and WWIII.
