Regarding the Defiant data base - consider the amount of information in the 'Help' files associated with most computer programs. While they don't tell you how it works, they provide some good explainations of the concept.
In the case of the 'help files' associated with engineering there would be a lot of valuable data just because the explainations for repair would of necessity cover a lot the the design concepts.
Most ships would have training modules incorperated that would be used for crew education. These would most probably give a lot of background information.
Since there seems to be a lack of 'paper' on these ships, there would be the equal of our encyclopedia - once again a lot of background data.
Remember while the Defiant is 100 yrs from the future, many elements of it's design were logical developments from the Enterprise.
(Quite honestly, I was suprised how quickly the Enterprise crew was able to take over and operate the Defiant. Just sitting down at the different consoles should have been more of a challenge. Also, I can't imagine that there was no security in place. You shouldn't be able to access all those systems without some sort of 'log on'. Wasn't it a practice to erase the computer banks if the ship was in danger of being captured?)
