This sounds memory-intensive, which I think is likely to do more harm than good.
This request sounds similar to when people ask for a more comprehensive in-game chat feature when Discord already provides everything a guild could want.
A solution to what you’re asking for already exists outside the game (wookiepedia), and if someone wants the information it isn’t difficult to go to that website and read it there. There’s a long list of things the game needs (mod snapshot capabilities, improved datacron UI for instance) more than incorporating a database feature that already exists elsewhere.
It's possible it would be memory-intensive, but games like CIV or Crusader Kings have done similar to this without huge memory leaks (at least to my understanding). Usually via linking to a webpage or something in a connected browser.
The data wouldn't necessarily need stored locally if there was a way to easily call it, especially if the device is on Wifi.
