Does anyone know where I can find some competitive information on the AS400 database engine - sql/400 ?? or whatever it's called now. As for OS2 - is it OS2 DataManager or SQLserver (is SQLserver Sybase or some special version of Sybase? ) Any info would be appreciated ! -Phil

What kind of competitive information are you looking for? The AS/400
database engine is not really a fully functional relational database,
it's more like a SQL-driven file system. They've had lots of problems,
such as multi-day recovery, difficulty in expanding/moving data spaces,
etc. I'm told that they've improved the system a lot in the last year
or so, though.
IBM's OS/2 database system is called the OS/2 EE Data Manager. It is
included in OS/2 Extended Edition. SQL Server is a joint effort by
Sybase and Microsoft, and it runs on Microsoft's vanilla OS/2 system.
SQL Server is much more popular than OS/2 EE Data Manager, although
OS/2 EE Data Manager is the so-called SAA-Compliant database for the
OS/2 platform.

Thanks Anne. Is SQL Server the same software as Sybase - I 'm wondering if you can easily port a SQL Server application and database to VMS running Sybase? I take it there is no competitive fact sheet on the as400 database - it being a glorified file system pretty much sums it up. | |||||

Phil,
Sorry. I've been travelling a lot recently, and I haven't been in here
in ages.
SQL Server is a condensed version of Sybase. I don't know how portable
PC or OS/2 applications would be to VMS. Sybase doesn't offer a
portable application development environment (like Oracle's SQL*Forms)
so I wouldn't expect that it would be all that easy to port desktop
SQL Server applications to a VMS Sybase system.
