Does Your SOA Include a
Persistence Strategy? By David Linthicum  Truth be told,
traditional approaches to
integration are really
about keeping persistence
at the points, within the
source or target systems,
and replicating data as
needed. However with the
use of true services,
there is a clear
advantage in keeping some
persiste... Dec. 27, 2005 02:00 PM Reads: 18,135 Replies: 5 | Brokering Web Services...
The Next Big Thing? By David Linthicum  Web services were created
around the notion that
it's easier to discover
and leverage somebody
else's service rather
than write your own from
scratch. Also, it is much
easier to create
applications made up of
many services, thereby
allowing change to occur
at a pa... Dec. 9, 2005 04:30 PM Reads: 20,503 Replies: 6 | Can Your SOA Web Services
Make You Money? By David Linthicum  Why do we do what we do?
I mean, why do we design
and implement SOAs? The
truth is we do so to
improve our business,
thereby making it more
adaptable and ready to
accept change without
major disruptions.
However, what does this
mean to the bottom line? Oct. 17, 2005 03:15 PM Reads: 16,155 Replies: 2 | Designing SOA Web
Services Services for
Performance By David Linthicum  As we discussed last
month, performance is
often an afterthought
when building new
systems, including SOAs.
We're finding that
services and SOAs fall
victim to this oversight
as well. Indeed, there is
a right way and a wrong
way to design a service
and an SOA. Als... Aug. 2, 2005 10:15 PM Reads: 18,243 Replies: 2 | Designing For Performance
- Keep Your Web Services
Up By David Linthicum  Performance is often an
afterthought when
building new systems, and
I'm finding that services
are no exception. Truth
be told, most services
out there just function.
They are not optimized to
scale, and SOAs are
running into walls as
those services hit the

the Context of an SOA By David Linthicum As we bring our SOAs
online using Web
Services, we all know
that SOAP is the
standards message
transfer protocol. But
the interface description
language for Web Services
(WSDL) isn't specifically
for SOAP. It's more
generic. Apr. 26, 2005 11:00 AM Reads: 15,001 | Understanding Coupling in
the Context of an SOA By David Linthicum Since the beginning of
computing we've been
dealing with the notion

application or an
architecture. Lately, the
movement has been towards
loose coupling fo... Mar. 18, 2005 12:00 AM Reads: 18,937 Replies: 2 | Could Enterprises Be
Pushing Back on ESBs? By David Linthicum I just got back from the

America, as well as the

that services-oriented

their own definition of

enterprise's Web

you'll be enabling or

surprise to anyone. Oct. 28, 2004 12:00 AM Reads: 16,095 Replies: 1 | Secrets of Designing a
Service By David Linthicum Software design has
always been a focus for
developers, but as we
cycled through different
approaches, standards,

the years, I think we've
had a tendency not to pay
enough attention to the
fundamentals of software
engineering. Clearly I've

Mobile Devices By David Linthicum Let's face it, we're

as you know by now, we

Ontology is a term
