A final (?) note on year calculation shortcuts:
Had Dick chosen jan 1 in a year divisible by 400 as day 1 then
INT(DAY / 365.247525 )
would have worked all the time.
But selecting a '400-year' starting on a sunday would result in quite
long internal dates unless year 2000 started on a

Because data storage is part of the Pick data model, we can be confident
that benchmark results are valid across all (similar?) implementations.

I don't have any idea what you are trying to say.
A database should be a black box. You put data in and pull data out.
The less you have to know about the details of what goes on inside, the
better.
You can easily benchmark two black box systems that perform the same

I understand your desire for a black box. The problem arises when your
black box is upgraded. I've come across anecdotes of eg Oracle upgrades,
where new software has resulted in a markedly slower system, because

Nick,

These are interesting comments considering all the tools available with IBM U2
and the many things they have in the hopper.

Yes. I have been a loyal U2 professional for many years and thought I
would end up selecting U2 for a new application.
Leroy,
I know IBM are implementing much of these new technologies with regard
to U2. The problem that I see is that it may be there, but a lot of the
people in the list cannot find information on how to use it either
because this information

Interesting thread. Even though I don't really have much to do with
UniVerse these days, I still enjoy reading (and learning from) these
forums.
I've been a long time user of both UniVerse and SQL Server. Developed
many things using one, the other or both db's as data sources. I

Well put. This is one of the issues we are running into. We are a .Net
shop, and going from .Net to UV has been a challenge to say the least.
The primary issue being the overhead associated with access the data via
uo.net. Performance just isn't good

A quick example is I'm trying to find out how their Connection Pool license
works.
Noone seems to know nor can I find out how this integrates with mv.Net using
UO.NET
as the connection. I can't find out how to configure a connection pool,
monitor the
connections, or anything else.

The detailed agenda is posted on the web site, now.

Bill,
If you are using MV.NET, it has its own connection pooling which is
pretty well documented. That being the case, you don't even need to use
the UO.NET built in connection pooling.
Thanks,

Bill,
mv.NET from BlueFinity would be using standard UniObjects and as such, could
not take advantage of connection pooling from U2 (CP). There may be licensing
implications with U2 that require one to acquire CP licenses to use mv.NET,
though.
In any case, it is a simple matter of changing
