Could you please throw some light on how the versioning needs to be done for
the proxy class?
One more question regarding the custom class:
I'm not sure what's the preferred/best method to retrieve the records from
the webservice. Which one is better when deciding to retrieve data from web
service?
1. Using Datasets (Multiple datatables can be returned. But could this make
the web service slower than when using custom objects)
2. Custom objects
BTW, when deciding to use custom objects. How should the records be stored
inside the object (I mean what's the industry standard or preferred method
of storing multiple records in a custom object?) Should a dataset/datatable
be used inside the custom object to store data or is there another better
method?
Another question/topic:
The architecture that I want to follow is GUI -> Web service -> Business
Objects -> database.
I would like the application to be highly scalable and load balanced.
Therefore I would like to scale it at the business objects level. If I have
multiple servers with the Business Objects installed/running. How could I
let the web service know
1. Which server to use (depending on load balancing.) BTW to load balance
should I incorporate any logic to the application/webservice?
2. How to supply/notify my web service at run-time the servers that have the
Business Objects running?
Thanks in advance for your valuable inputs.
