It would be helpful to have IBM salespeople know that Informix exists, and sell it. Currently, it is completely ignored by IBM.

In my opinion, the packages could be improved. The version I use doesn't allow for packages. I can do some general procedures, but no packages like in Oracle. So, develop separate modules in SQL language. This would be most beneficial for me.
