The definitions have a lot in common, so there is a good bit of overlap. I'd say that "database theory" is closest to definitions and #4, with a fair bit of definitions #3 and #1, and intersects with definition #5 only incidentally. Definitions #2, #6, and #7 are a completely different usage of the word.
