I did something similar when I figured out XSLT was for more than just front-end stuff. And I was working with Oracle as the database too; these enterprise code bases acquire huge amounts of often poorly written SQL and it feels like making at least some of the repeated queries DRY would help - but later you realize the people who need to maintain this system when you're gone are the same people who came up with the spaghetti queries in the first place.
