The mathematical formalism is not your biggest problem, altough it could certainly be improved (if you want I might be tempted to help), but what seems to be missing is a decent understanding of what all the math exactly means. What is the intuition behind your approach? Why would it make sense? You hint at this with the interpretation function I, but this should not be a side remark in the middle but rather the foundation and justification of the rest, and that doesn't seem to be there.
You may also want to Google my name, to see why I think I can get away with being so arrogant. ;-)

A final tip. Decent database theory doesn't come in Word. It comes in LaTeX. :-)
