There are so so so so many reasons for this. Research data: hard to centralize because subject to impossible conflicting demands from funders and human subjects IRBs, and in the hands of ferociously independent faculty. Students: privacy laws and worse than that over-cautious university counsel and administrators who are afraid of running afoul of those laws. Administrative data: stuck in a bunch of individual bureaucratic buckets that don't talk to one another because universities are badly managed in general, also in the clutches of horrific enterprise software platforms made by the worst companies in the world (like oracle) and administered by IT people who aren't paid market rates. University data projects tend to succeed if and only if they're turned over to librarians, who are typically the only people on campus who have any clue how to do such a thing.
