My experience with AIM* is that its not so hard. Installation is generally
the biggest issue. One does have to follow the directions pretty closely.
I'm not so sure how to compare AIM* to Informix since one is a historian
with ODBC/OLE DB support and the other is a true Relational Database.
AIM* does have reduction groups. It also has the ability to calculate (fake)
reduction groups during a data request. This is useful if you don't need to
keep reduced data around.

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.
