I am not familiar with UniData and I am aware that UniVerse has had better SQL 
support than uniData.  I have found that UniVerse SQL performs well.  The 
UniVerse query engine is used by both SQL and retrieve, where they pass the 
query over to an optimizer engine.   One thing that has been a bit slow is the 
ODBC driver which has been updated at release 11.1 .   Also the query 
integrates with EDA, so I can be selecting data off a UniVerse, Oracle and SQL 
Server at the same time.   I would be interested in comparisons in performance 
of a similar data file with similar indexs, triggers, etc.  There is also a 
consideration issue whether systems are designed for fast retrieval or fast 
update.  It is difficult to assess query performance, we all know how 
meaningless the old TPS tests were that the RDBMs used to quote all the time.

I agree with Dawn some of Caches object model for data is quite innovative and 
how it propagates to client tools is nifty.

With IBM U2 was under resourced, with Rocket U2 has better resources and it is 
in a much better position to advance quickly with new innovation, it is now 
time for ideas.
