Re: [foxboro] Informix Historian vs AIM*

Thanks, Alex.  Two questions:
    1.  How is the ease-of-use of AIM* compared to Informix?  My understanding
is that AIM* is capable of many things, but this unfortunately makes it complex
to wade through.

    2.  Does the AIM* have reduction groups?  My understanding is that a
reporting application would need to do the reducing itself.
