ARC SymposiumThe symposium itself was based on a skid that covered
topics ranging from SOA to Agile to process and domain modeling.<br>
One might laugh at such a simple language syntax but it definitely did
the trick and it only took less than a day to code up the parser.<br>
Interestingly, though, some talks also focused on areas where objects
would be very useful but are not utilized.<br>
Maybe the writing was on the wall that I wanted to write about
integration some day! I think many people went through that experience
with attributes not too long ago. Sounds not that exciting?<br>
Even I could not resist at the time and created InfoGate.<br>
In a nice acknowledgment to Constantine and Yourdon 's work , Kent Beck
remarked appropriately that "People who could not do a decent job with
structured design went to objects so noone would notice.<br>
Nevertheless, having a catalog of named patterns allows many developers
to talk about the same concept by the same name. Calendar you have to
specify all assumptions that are made implicitly by Calendar, such as
the time zone.<br>
For my purposes let it suffice to say that the goal is to develop an
expressive model of the problem domain that can be closely reflected in
the resulting source code.<br>
In short, external DSLs define a new language from ground up. If you use
an attribute, you need to decide whether you want to allow multiple
methods to be marked this way and, if so, what the desired behavior is.
The principle behind the shift in responsibility is once again tied to
the concept of coupling. Time and MoneyEric Evans developed an open
source Time and Money library that he uses in projects and also in his
training classes.<br>
Arriving at the event Sunday evening, I quickly realized that this would
become an interesting week. The symposium included the demo of a tool to
allocate logical services to the physical infrastructure.<br>
com - allows you to check prices over your phone and then look up your
history over the web site.<br>
For now I'll simply refer to a higher authority.<br>
Service MixQuite a while ago I blogged about my experiments
implementing the patterns in our book as executable components.<br>
