Hi everybody,
usually I'm just a listener on this mailing list, but this time
I'd like to express my opinion. I see you're talking about VB and,
as it seems, an in house application. Then you speak about SOAP, DCOM
and CORBA. If you are making in house applications in VB, you can use
available tools without issuing to XML or SOAP. If you use a
client/server
approach, you can use the ODBC driver to access a Postgres server. If
you're
thinking to adopt a three-tier approach, you can build the middle tier
in
VB over a WIN2000 server (God save us!) and still access you Postgres db
over ODBC (in fact, it would be much better if there were a OLE-DB
driver):
the business rules are the most important part of your system and if you
know only VB, well, I can't see any other solution.
SOAP, Biztalk and the other MS appraches to platform independent
communications are geared toward business to business communication,
when
you need to access informations and applications that are located
remotely,
maybe on a different platform, but surely with a different information
structure (the same db will be designed with different tables by
different db experts), so there's a different context. In conclusion, I
don't think that one needs SOAP for in-house development. You must also
consider that XML creation, decode an transmission requires bandwith and
processing time, so it's not as efficient as an ODBC/OLE-DB driver.
I hope this helps.
