RE: DB2

[Gord Royle <GRoyle@xxxxxxxx>]

You're asking a lot to go back many , many years. At my age, my memory isn't
that good. As far as I know, there never was a db1. IBM actually changed the
name at one point to DB2/UDB to try to sell us on the fact that DB2 was the
same whether it was on the PC, AIX or the 400. In fact, the SQL is the same
(or almost) but the underlying database isn't. On the other hand, if you're
talking about DB2, I guess that, unless you're the DBA, you don't care much
about the structure, you just write the same SQL code.

The iSeries - or for us Luddites, the AS/400 <g> - has always had a database
as part of OS/400.

At some point IBM decided to give that database a name and as other db's on
the PC and mainframe were called DB2, the obvious choice to conjure up an
image of "oneness" was to call it DB2/400. In fact it was pretty much
similar to the S/38 database.

But this only lead to confusion as DB2/400 is nothing like DB2 on the PC or
DB2 on the mainframe.   I am sure others on this list will provide more in
depth knowledge of the subject.

It begs the obvious question: was there ever a DB1?

How many years has the 400 been using db2?  Is that an option or is it the
database management software that every machine is shipped with?
