You're confusing terms here. In the Windows world, the term "native
I/O" does not exist - it's called "I/O". Mainly because Windows lacks
the integrated database and multiple filesystem support that i5/OS
has. A direct mapping between i5/OS and Windows would be "I/O" vs.
"IFS Stream File I/O" (even that isn't entirely correct, because you
can access DB/2 through the IFS).
Joe has said much of what I'd say, so I'll leave most of that out.
Personally, I stepped into the System/38 after programming under the
Pick OS implementation on Microdata Reality systems. No need to list
all the different platforms (H-P, DEC, and others) I have experience
with.
After catching on to the S/38 and CPF and what IBM(Rochester) was
doing, my interest hasn't wandered. But that's not the same as never
looking elsewhere. Why do you think I was able to create my own SQL
Server database to test against so easily?
It's irrelevant.
What you missed were the quotes I put around "native I/O". I used
them because I was responding to the way the term was used way back
near the beginning of the thread/discussion. It wasn't my term. I'm
indicating that I'm discussing the concept that was presented and
that I'm trying to get an answer from Dave on what /he/ means by it.
No answer yet.
Tell Dave that he's using the wrong term or using it wrong; don't
tell me.
I'm pretty sure that he means something about how _programmers_ are
allowed to code programs. But it's not clear at all because
_programmers_ can write code on Windows as well as on whatever
systems run Oracle or any other "real RDBMS".
I'm looking to understand why DB2 for i5/OS is inferior because it's
in control for "native I/O (whatever that means)" when other RDBMSs
are not.
And I noticed that you didn't provide an answer for that either...?
Open your eyes. Open your mind. Look at other platforms. See how they
work. See how they solve problems.
Remember, different doesn't mean worse.
After some 35+ years, believe me -- I've seen just about all of
them. Remember DYL260? Remember coding for ISAM access under M/PM?
How about OS-65U and switching between the various processors they
made available, from 6502 to Z-80 and back in a running
application? (I still have an OS-65D system, a C4P, that works.)
Oracle on DEC has been a few years gone for me, but I remember how
it used to be. Is Forth available for System i? THAT was fun stuff!
But that's old news. Today I need to know about SQL Server, etc.,...
Fine. Dave knows such stuff in detail, enough to consider DB2 under
i5/OS not to be "real". He gave reasons -- one of which had to do
with "native I/O". It seemed to be an important reason, but it
wasn't defined in any useful sense.
I'm hoping to be educated by him about it so I can understand his point.
Maybe you can explain...
