Normalized ER diagram + notation + data dictionary
I worked with Showkat on an ERD task a couple of years ago and his delivery was exceptional. The final document was neatly formatted, clearly organized and, most importantly, extremely well-done.
Cannot recommend him highly enough for anything related to data.
