 Hi,

I hope I haven't sent this questionaire to you already.
Ignore it if you have seen it already.

On the net I noticed that you work for Informix.
I have a couple questions that perhaps you could
answer or pass on to someone who would know more.

My professor and I are doing research in fault-tolerant
information recall.  This means that a data base query
will always recall information in the presence of 
faults. If data is corrupted in the query and/or data
is corrupted in the database, searches will always 
return the "best" match.

We have developed an SQL RDBMS prototype that
exhibits very high recall rates (high 90% for single
errors). We feel that this technology could be very
useful in OLTP systems (airline reservations, library
searches, law enforcement, banking, financial) where
human users under pressure tend to make mistakes and
create corrupted information. This technology also solves
problems associated with corrupted foreign keys in 
Join operations.

My questions are:

	1) Have you ever heard about this type of
	   technology before? 
	2) Have your customers ever asked you about
	   this capability
	3) Do your products address the problems 
	   associated with corrupted information?
	4) Do you feel that working with corrupted
	   information is/will be a problem as the
	   need of OLTP grows.
	5) Would your company be interested in this
	   technology?


I would appreciate any help you could give me in answering
these questions.  Thank you for your time.
