I am not sure some kind of AI based automat can sort it out properly. I too, ended in situation when I obtained mainframe csv file, not knowing the structure. We did it manually that way - we started to define .dbf file, guessing what the structure could be. What helped us was, we knew what some data mean/represent (e.g. recognising customer name, contract description, etc.) ... So, I can leave this thread, as I have really no knowledge of how to build the system you described. I have even never seen something along the lines of AI automat digging into some data .... -pekr- > > >-jn- > -- To unsubscribe from this list, please send an email to [EMAIL PROTECTED] with "unsubscribe" in the subject, without the quotes.
