For someone who includes "English is not my native language" in the footer of every post, you have a very precise and rigid definition of the word "integration."
BTW, on the subject of proper English, I think you mean to use "still" rather than "steel" in the first paragraph of #19.
Anyway, I'm not an IT professional/developer, but I have a more expansive/inclusive definition of "integration" and "interoperability." But a debate on semantics isn't really something that interests me.
