1. Delphi 2.0 vs. JAM vs. Powerbuilder 5.0
Powerbuilder 5 and Delphi 2 are new, so there aren't many head-to-head articles
about all three yet, but for JAM and Powerbuilder, look at Unix Review (May and June).
MacWorld (Oct-95, Aug. 96). For JAM only, try DBMS Mag. (Nov-95), PC Week (Sept 4-95),
and Infoworld (Sept 25, 95, June-17, 96). The JYACC web-site has more (www.jyacc.com).
Also, there are analyst reports from the Gartner, Standish, Giga, etc, but these
get expensive. The vendors should have copies they can give you if you contact them.
Below is some info I have about all three, but I've only built apps with JAM, and
not with Powerbuilder or Delphi (plus I work for JYACC, so there is a bias here ;-)
JAM runs on Unix (SunOS, Solaris, HP-UX, AIX, DG-UX, etc) in both character-mode
and Motif, on Win-31, Win-32s, Windows-95, Mac (6800 and PPC), OS/2, VMS,etc It has
native drivers for Oracle, Sybase, Informix, ODBC, and close to 20 other databases.
JAM 7 has been shipping since last fall?, and JAM has been sold for over 10 years.
JAM has a Web Interface, and can be deployed across multiple-tiers (it was one
of the first tools to interface to Tuxedo), and you can build the other tiers in JAM,
if you want, or in C with native Tuxedo calls, or C with JAM C/Tuxedo calls.
Delphi 2.0 natively compiles on Windows. It only runs on Windows (95?). It is Pascal
based, and is pretty popular on the Windows platform. I am not sure if they've done
a Windows-95 port yet, but it should be coming soon if it isn't here yet. I am not
sure which database drivers are available, but they should have drivers for ODBC and
probably Oracle and Sybase, perhaps more. It is the youngest of the three tools.
Powerbuilder natively compiles on Windows. It runs on Windows (3.1? 95?) and Solaris.
I think it has native drivers for most databases if you are a Windows user, but on
the Unix side I think they only have a Sybase driver out. Powerbuilder is very
popular on the Windows platform, and there are lots of third-party add-ons available.
For information about JAM, try www.jyacc.com (free eval copies of JAM and JAM/Web)
For information about Delphi, try Borland.
For information about Powerbuilder, try Powersoft or Sybase.
Feel free to contact me if you have any real-life questions (Can JAM do this? etc)
or contact the sales folks at JYACC.
