I'm sorry but you seem to not understand what data integrity is if you think Excel is a perfectly acceptable solution here.

It's all about the use case, man.

Within its constraints excel is great. Depending on the nature of your data and exactly what you are trying to do it can accomplish quite a bit.

The line between when to use excel and when to build custom stuff is not as clear as it seems, is all I'm trying to say.
