, I certainly did not feel insulted or offended. The questions you asked are legitimate and you don't need to apologize. I only wanted to point out that if there is one technical subject that I really know well, inside out, it is this database and the application around it (including the different (at least 3, in some cases 4) levels of abstraction between the database level data types and the lowest, architecture dependent, level data types). So that I know that what I said about the data types used on this application is really accurate. But again, I certainly did not feel offended, no problem for me.
