Hi !
I have to develop an accounting soft solution. For many reasons we decided
to use a three tier architecture. The logical tier is composed of logical
components and a web service facade that delegate to the logical components.
The presentation will be composed of both a widows forms application and a
web forms application. Both applications will access the web service facade
either through Internet or an intarnet. Of course, an accounting software
solution will have a HUGE quantity of datas to be transfered to the
presentation layer...
My question is: are web services a good way to implement the facade of the
business layer ?? Will it be ok to transfer huge amount of datas to the
presentation tier ?? If no, how would you design such an architecture ??
Thanks for any help !!

Huh... HUGE quantity may be relative term. I suggest you to use more
techniques and test the results. Web Service that returns DataSet or more
simple types, Install WSE (Web Service Enhencements) and try using DIME
protocol... Try VPN and directly connect to SQL... You will see that WS can
also be slow within intranet.
In any of these ways it will be slower if the amount is HUGE.
the other question I see here is:
Can HUGE ammount of data be considered as good user experience design? Could
the process of this be somehow split into smaller chunks of data? Will the
user REALLY use the whole set of result (in more than 50% examples) or will
he/she use only a part of it most of the time... How will user effectively
navige this huge set of data? Will he be interested mostly on some sorts of
results produced by this data?
So there are many questions you should ask yourself before implementing a
solution like this.
I suggest you answer the upper questions correctly and after that
performance test test test...
